How to Make It
Preheat the oven to 400°. In a large nonstick skillet, cook the bacon over moderate heat, turning once, until browned and crisp, about 5 minutes. Transfer to paper towels to drain, then break the slices in half.
In a medium bowl, beat the eggs with the milk and a generous pinch each of salt and pepper. Wipe out the skillet and melt the butter in it over moderately high heat. Add the eggs and cook, stirring frequently, until small, soft curds form, about 3 minutes.
Arrange the tortillas on a large baking sheet. Spoon the eggs on the tortillas and sprinkle with the cheese. Bake for about 3 minutes, until the cheese is just melted. Top the eggs with the bacon and avocado. Serve right away, with radishes, cilantro, white onion, lime wedges and hot sauce.
