To make the Ranchero Sauce:
In a medium pot, heat the oil over medium-high heat. Add the onions and bell peppers, and cook,
stirring, for 3 to 5 minutes. Add the cumin, salt, cayenne, jalapeno, and garlic, and cook, stirring, for
30 seconds. Add the tomatoes and their juices and cook, stirring, for 2 minutes. Add the stock and
simmer until thickened, about 15 minutes. Remove from the heat and add the cilantro. Adjust the
seasoning, to taste, and cover to keep warm.
In a large skillet, heat 1/2 teaspoon of vegetable oil over medium-high heat. Add 1 tortilla and cook
until warmed through and just starting to brown about 30 seconds. Turn and cook on the second side.
Remove, cover to keep warm, and repeat with the remaining oil and tortillas.
In 2 medium skillets, melt 1 tablespoon of butter each, over medium-high heat. Break 4 eggs into each
skillet and fry until beginning to set, about 1 minute. Sprinkle the eggs with the cheese and cover to
finish cooking, about 1 1/2 minutes.
Place 1 warm tortilla on each of 4 plates and spread each with 2 tablespoons of warm refried beans.
Place 2 eggs on top of each tortilla and top with the warm Ranchero Sauce. Serve immediately.
