These are a good 'what's in the fridge' kind of meal, all you need is Tortillas and Eggs to call it 'Huevos Rancheros' but these would be my ingredients.
Eggs, Fried Over-Easy
Guacamole or Avocados
Fry the Egg, this was a failed attempt, I like them over-easy.
Make a Salsa Fresca (or cheat and use Salsa) with the Tomatoes, Onions & Garlic.
Mr. M's Guacamole, the recipe is a secret.
And Black Beans, I just bought a can, drained them and warmed them up on the stove.
