In a medium skillet, over medium heat, cook the crumbled breakfast sausage or bacon until it’s fully browned, approximately 5-7 minutes. Remove the meat and place it on a paper towel to absorb excess grease, reserving about a tablespoon of the fat in the skillet.

In a mixing bowl, whisk together the 4 large eggs with salt and pepper. Melt 1 tablespoon of unsalted butter in the reserved fat. Once bubbling, pour the eggs into the skillet, stirring gently. Cook until just set but still creamy, about 2-3 minutes, then remove from heat.

Char the tortillas in the skillet or on a gas burner. Lightly brush each tortilla with 1 teaspoon of vegetable oil and heat each for about 30 seconds on each side until warm and slightly crispy.

Lay the tortillas flat and start with a layer of shredded cheese, followed by the creamy scrambled eggs, and then the cooked sausage or bacon. Top with avocado, fresh salsa, chopped cilantro, and lime juice.
