I love the convenience of frittatas. They are quick and easy to prepare and are ideal for batch cooking.

Mexican chorizo, which I used in this recipe, may not be available where you live. You can substitute it with a combination of Spanish chorizo and ground pork. Compared to Mexican chorizo, which is made with raw ground pork flavoured with spices, Spanish chorizo is cured or smoked sausage similar to pepperoni.

If you want to make your own Mexican chorizo in a few easy-to-follow steps, check out my new Quick Keto Book. I always keep a pound or two in the freezer in 2-serving ziplock bags. Because it's already flavoured, you won't need to use more than just a few ingredients to make a quick meal like this frittata or Keto Mexican Breakfast Hash!

Serving Suggestions for Frittatas

Frittatas can be served on their own or with a side of:

  • diced avocado, cherry tomatoes or peppers
  • sour cream or crumbled feta cheese
  • Guacamole - you can make your own
  • Sriracha sauce - you can make your own

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.
