I always thought my grandmother invented this, until one of my best friends was telling me about a great dish she had at a Mexican restaurant for breakfast. I have since seen it, and had it, at several restaurants. In any case, it is fast, easy, and oh so good! I have made variations adding in chopped onion, bell pepper, mushrooms, herbs, etc. In a pinch, I have substituted tortilla chips rather than frying fresh tortillas myself, and it was good, not quite as good, but good. Don't be afraid to experiment! Also, I don't measure a lot when I'm cooking, so these are "guesstimates". However you decide to make it, just make sure you have enough egg mixture to cover everything else. The eggs should make up the larger portion of the dish. This is simple, but big on flavor! Enjoy!
