Step 1 1. Melt the butter over medium heat in a large nonstick skillet. Add the green onions and cook until they wilt slightly, 1 to 2 minutes. Add the green chile and cook until fragrant, another minute or two.
Step 2 2. Add the beaten eggs and let sit until they just begin to set, about 1 minute. Salt lightly, sprinkle the tortilla chips over top of the eggs and stir, folding the unset egg over the chips. Cook quickly (to keep the chips from softening), stirring until the eggs are almost set, then stir in half of the cotija cheese.
Step 33. When the eggs are set to your taste, an additional 2 to 3 minutes, divide the mixture evenly among 4 to 6 heated plates, or serve it family style on a large platter. Spoon over the black beans, then the remaining cheese, sour cream and the cilantro. Serve immediately.
