2 tbsp oil or lard
2-4 corn tortillas, torn into medium sized pieces
About ¼ cup chopped onion
1-2 green chiles, seeded and chopped (optional for those who want some heat)
¼ cup cooked salsa, green or red
3-4 eggs, lightly beaten
In a medium sized skillet, nonstick if possible, heat the oil and then fry the tortilla pieces until the start to crisp a bit, stirring often. Remove from pan and drain on a paper towel. Add the onion and green chile if using and cook until tender, add the tortilla pieces, the eggs and salsa, cooking until eggs are done, stirring as needed. Dish up and eat!
You may add some chorizo or diced ham when frying the onion and chiles. You can top with grated cheese if you like, but I really think that isn't needed.
