This is a ridiculously easy breakfast (or breakfast-for-dinner). It's not a recipe, just a recommendation born out of my deep love of Reyna's corn tortillas.
Prepare one egg per person in whatever way you like.
Take two tortillas per person - using a hot griddle or skillet (clean - no oil), place one tortilla on the skillet and cover with a thin layer of cheese, then top with the other tortilla. Cook for about a minute on each side or until the cheese is melted.
Take it off the heat and top with an egg and whatever else you've got: salsa, cilantro, green onions, more cheese, black beans, veggies, pre-cooked meat, etc.
