Fry tortillas. Heat oil in a large frying pan or cast iron skillet over medium-high heat. Once hot, add tortilla strips and let cook until very crisp, stirring occasionally, about 6-7 minutes. Season with salt.

Add veggies. Add onion and bell pepper and season again with salt. Reduce heat to medium and cook until veggies are just getting tender, about 2-3 minutes.

Add egg. Reduce heat a little bit more and pour the beaten eggs over everything. Season once more with salt and stir eggs into the migas. Let cook until eggs are mostly firm but still a little runny in spots (they will finish cooking off the heat).

Add cheese. Sprinkle cheese over the top, cover and remove from heat. Let sit about a minute or so until the cheese melts.

Serve. Serve immediately with the garnishes. You can put them on top of the whole dish or let everyone top thier own plate as they wish.
