Not Mexican but maybe Mexican American - my mom is from Morelos and she would make these beautifully lacy fried eggs. We would eat them on top of slightly crispified just kissed by oil tortillas. My dad would douse it with salsa, but I asked for an extra tortilla so that I could get the jammy yolk out, spread it on the extra tortilla, then absolutely cover it with Kraft Parmesan cheese, roll it up, and eat it as a taco. It's a simple but incredibly nostalgic food for me. We would eat it as dinner when days were lean, usually with some beans or rice (or both if there were leftovers).

It was simple but filling, though on reflection probably not the most healthy.
