Add 1 tablespoon vegetable oil to the fat in the skillet. Place a tortilla in the skillet and cook until light golden but not crisp, about 30 seconds. Flip and cook for 30 seconds more. Transfer to an individual plate. Cook the remaining tortillas, adding a bit more oil to the pan if necessary.
Heat the refried beans, if using, in a small saucepan. Spread the beans on the tortillas.I have used a chilli that I made with black beans and kidney beans and loaded with veggies
Add another tablespoon of oil to the skillet. Working in batches, crack the eggs into the skillet. Cook until the bottoms are set and the edges golden, 1 to 2 minutes. Turn the heat to medium-low, cover and cook until set, about 1 minute more. Place some lettuce on the tortillas followed by beans or chilli ,sauce top it with 1 egg. Sprinkle with the avocado, cheese and additional cilantro. Top with a dollop of sour cream. Repeat with the rest of tortillas.
