Char tortillas in a dry nonstick or cast iron pan over medium-high heat. You can also char over an open flame if available. Set aside on a plate.
Fry eggs in a nonstick skillet over medium heat, using 1 teaspoon of vegetable oil. Fry to your desired temperature, I prefer medium.
Place two tortillas stacked on a plate, add your warmed beans, then a fried egg. Add your favorite garnishes such as queso fresco, salsa, cilantro, and avocado.
Notes
Top with any of your favorite toppings.
You can use flour tortillas if you'd like.
You don't have to char the corn tortillas, you can just warm them up in a nonstick pan if you prefer.
