I never thought about having a taco for breakfast until I moved to Texas. Now, I can't imagine NOT making a taco for breakfast! I make this casserole on the weekend and keep it in the fridge. Then my husband and I take out what we want in the morning, heat it in the microwave, and throw it in a whole wheat or regular tortilla with some salsa or verde sauce. We we are out the door with a healthy breakfast in no time! He didn't realize it was soy chorizo until after I had made this about 6 or 7 times. You can serve the casserole as it is for breakfast, or use it as a great taco or burrito filling for a grab and go breakfast.
