Tips and Ideas

Add More Fat

Eggs may be the perfect protein, but if your goal is to have keto macros for every meal, then you'll want to add more fat to your egg slices.

Firstly, you don't need to have perfect keto macros for every meal. So, you don't need to add fat.

However, if you want to add fat, add half an avocado. That can easily double the quality fat in this meal. 

If you don't mind dairy, replace the almond milk with two tablespoons of full fat cream or add a tablespoon of butter.

Or add a few ounces of grated cheddar cheese on top of your slice.

This is a small breakfast meal that you can easily turn into a substantial meal if you add more fat.

Use up those Unused Ingredients

Have any peppers or zucchini that you don't know what to do with? Add them to your slice.

With zucchini make sure they are dried probably. You don't want your egg slice to become watery. 

Have excess zucchini? Then you'll probably want to check out these zucchini recipe ideas.
