This keto fish salad is one of my grab & go favourites. It's great for anyone with a busy lifestyle looking for a sating and nutritious low-carb meal they can take to work.

I always have hard-boiled eggs and keto-friendly mayo in my fridge. This way I save time and money and avoid temptations. If you want to succeed with your healthy low-carb eating, you should plan your cooking at least a few days in advance.

To avoid unhealthy vegetable oils that may often be used in tuna products, get tuna in extra virgin olive oil or in brine. I avoid buying canned foods and get tuna in glass jars instead. This will minimise your exposure to toxic BPAs that may often be present in canned foods.

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'm assuming oil and the lemon juice is the dressing? you have lemon juice listed but not mentioned in assembly

Thank you for letting me know, Mike. It is mixed with the mayonnaise and added in step 3.

This is great! I have to cook for the whole family and it's always not easy to cook food separately. It's very quick, I don't feel hungry and its's low in carbs 😊 My hubby and kids are not into paleo or low-carb, I wish they were :-/

I think you can always find meals that are healthy and paleo-friendly that you can cook for the whole family. I guess it's the grains they don't want to give up. Even if they don't eat 100% paleo, you can always add more vegetables, healthy fats and avoid processed foods.

I love tuna salad! It's actually my staple food I take to work. Done is no time and so filling 😊

Thank you Kate, it's same for me, it's my grab & go keto meal!

Never thought of using spring onion for less carbs! Thanks for sharing 😊

I've been using spring onion and chives for a while now and it's great for saving carbs!

Love these simple recipes! I made my first home-made mayo yesterday and couldn't believe how easy it was. I used macadamia oil, as it tastes very mild and has healthy fats. I will never go back to Hellmans :-D

Thank you! Macadamia oil is my favourite too 😊
