Add 2 corn tortillas to a quarter-sized baking sheet. Take 1 tablespoons of oil and fully brush each side of the tortillas. Salt them to taste.

Place them in the oven and bake for 10 minutes, until they are crispy.

While the tortillas are baking, add ½ cup of enchilada sauce to a nonstick skillet over medium heat. Add 2 eggs to the enchilada sauce and cook until the whites are fully set.

How to test eggs for freshness: Unsure if your eggs are still fresh to eat. Simply drop them in a glass of water. If they sink, they are good to go.

Divide the ½ cup of black beans between the 2 crispy taco shells. Add an egg on top of the beans and divide sauce between the shells. Divide the ½ of avocado, ½ cup chopped lettuce, 2 ounces Cotija cheese, 1 tablespoon sour cream, and 1 tablespoon chopped cilantro between the tortillas.

How to ripen an avocado: Quickly ripen avocados by storing them in a closed paper bag with an apple or a banana. They should be ready to eat within a day.
