I always keep eggs, avocados, bacon and mushrooms in my fridge and that's all you need for this recipe!

This keto recipe is perfect for those of you who looking for quick low-carb meal. You just need an egg, bacon, mushrooms and avocados. Feel free to add or substitute any of the ingredients with spinach, tomatoes, sliced cheddar (or any cheese), gluten-free Italian sausages, smoked salmon or add an extra egg!

Avocados are so healthy! They are low in net carbs, rich in fiber and heart-healthy monounsaturated fatty acids. They are very high in potassium which is often deficient in low-carb diets. Just one average avocado has less than 4 grams of net carbs and half of your daily potassium!

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I love your recipes, everything is so easy to make. 😄 A yummy tip for you: Slice the avocado and cook it in the bacon grease/butter just until warmed, omg the flavor goes way up it's delightful.

Thank you Mekka, that sounds like a great idea, will try! 😊

Hi. How do you cook the spinach with this please? Many thanks

Hi Amy, you can add it to the pan and cook until wilted - this will take just 30-60 seconds. I hope this helps!

How many carbs are in this meal all together.  Is is 6.6 net carbs?

It is 6.6 g net carbs per serving (the recipe is one serving). I hope this helps!

I’m a vegetarian.  What can I substitute for the bacon please?
Btw-love your plan and have your 14 day vegetarian plan too.

Thank you Jen! I suppose you could use 1-2 slices of cheese or a few almonds (both are good sources of protein and fat).

I love your new book with all the helps for us with food sensitivities.You have done more to promote a healthy lifestyle than anyone I am familiar with.
I have one request. Please offer substitutions for even more foods. You rely heavy in your breakfast and baking recipes on hemp and chia seeds. According to my IGg results, I need to avoid them, also ginger, eggs, wheat, gluten, cherries, pineapple and all dairy. My husband has different sensitivities: Almond, Beef, eggs,dairy.
So any help in the way of food substitution would be helpful. thank you

Debbie, thank you so much for your lovely feedback! I will keep that in mind and offer options where possible. That is a lot of foods you have to avoid! I'm planning to add even more filtering options in recipes: Recipes
I don't use hemp seeds that often, maybe apart from a few recipes, but I do use chia seeds in many sweet breakfast options. I will aim to provide a wide variety of different options. Thanks again!

Hi Martina.
How do you store your cooked bacon?

Hi Ava, I store mine in the fridge in an airtight container or in the freezer (if making large amounts that I don't plant to use within the next 4-5 days).

Do you wrap it in anything before putting it in the airtight container? I wrapped my cooked in the paper towel that held the bacon. Cold, it greasy paper!

I don't - I put it straight to the container 😊

Hi Martina,
I sauté greens in bacon fat and use all the fat from bacon for my breakfast. Am I supposed to do that?
Thank you!
PS: love your blog! Thank you for sharing your keto life with us🙏😊

Thank you Sasha! Yes, you can use bacon fat for adding flavour to your greens 😊

I do this on the weekends.  Rest of the week I do bulletproof coffee or bulletproof tea.  I have been plateaued for 3 months now.  I think the problem is that I go overboard.  so instead of 1 egg like you have, I eat 2 EGGS with avocado and spinach and oil and turkey bacon... This holds me for some hours but no more than 4 -5 hours. 😞

Hi Jannet, do you eat enough protein? If you feel hungry, lack of protein is the most likely cause: KetoDiet Buddy - Easy Macro Calculator for the Ketogenic Diet You may also want to skip the BPC for a while.

Can you recommend a substitute for avocados? I'm allergic :C  

It depends on what you can eat and what you like. I'd think an egg or a handful of macadamia nuts or a piece of cheese instead. Or you can make cook some spinach and add butter on top.

I just don't like there something I can replace it with?

Hi Wendy, try some cheese or eat some macadamias - they have a similar nutritional profile 😊

If you don't like mushrooms (and never have) is there an alternative to them in this dish that give the same benefits? I love everything else!

Yes, I think you can use any non starchy vegetables - spinach, kale or cabbage 😊

Research has shown that the greatest concentration of carotenoids in avocado occurs in the dark green flesh that lies just beneath the skin. You don't want to slice into that dark green portion any more than necessary when you are peeling an avocado. For this reason, the best method is what the California Avocado Commission has called the "nick and peel" method. In this method, you actually end up peeling the avocado with your hands in the same way that you would peel a banana. The first step in the nick-and-peel method is to cut into the avocado lengthwise, producing two long avocado halves that are still connected in the middle by the seed. Next you take hold of both halves and twist them in opposite directions until they naturally separate. At this point, remove the seed and cut each of the halves lengthwise to produce long quartered sections of the avocado. You can use your thumb and index finger to grip the edge of the skin on each quarter and peel it off, just as you would do with a banana skin. The final result is a peeled avocado that contains most of that dark green outermost flesh so rich in carotenoid antioxidants!

Thanks for your insights Jeante! I like eating mine with a spoon directly from the peel 😊

This looks like a brkfst from the gods to me! Love portobellos.
Can't wait till I can try eggs again...hopefully I will tolerate them, I eat 3 a day usually lol
My favorite brkfst in the world is beans, greens and fried or poached eggs on top (bacon optional). I feel phenomenal after eating it and it keeps my energy high for hours! I know beans are out for ketogenic diets; jus sayin' 😊

Thank you Helen! How about green beans cooked in butter /ghee? 😊

Grn beans just ain't tha same, Martina. I make AWsum legumes. Hamhock, onion, celery, garlic, bay leaves, parsley and kombu for the unami 😊 Then s&p and vinegar or tabasco sauce once they're done. Eat em all by themselves. I am one of those ppl for whom overeating beans is a distinct possibility. I eat them daily when not lowcarbing. I think my real parents must have been Latinos lol

Yes I know they're not the same and I miss them too sometimes 😊

Yummy, I love quick keto ideas! I hope you will post more of these in the future 😊

Thank you! We are planning to include more simple snacks - the truth is not many people have time to cook these days and need more easy, quick and healthy recipes!
