In a medium skillet, brown the meat over medium-high heat, if using.

In a separate skillet, add a light layer of oil to the bottom of the skillet and heat over medium-high heat. Add a few tortillas at a time and lightly fry on both sides. Remove from the skillet and keep in a warm place.

Add the sauce to a small saucepan and warm over medium heat. If using Fresh Chile Co. Sauce, stir in a little water until you reach the desired consistency.

Pour a layer of sauce on the bottom of 4 oven safe dishes. It’s best to use a deeper dish or shallow bowl, to keep all the ingredients in. Sprinkle a generous layer of cheddar cheese on top and top with 1 tortilla. Repeat to create 3 layers, finishing with a generous layer of the Asadero cheese. Top with onion. Note, if using meat, add in between the layers.

Place the dishes in the oven and bake at 375 or broil until the cheese has melted and bubbly.

Meanwhile, melt 1 to 2 tablespoons of butter in a large skillet over medium heat. Sprinkle in a little salt. Fry the eggs to desired doneness.

Remove the dishes from the oven and top each dish with eggs. Serve warm.
