Drizzle half of the egg mixture over the top of the cheese.
Repeat by laying down the remaining chiles, shredded beef, and black beans.
Drizzle the remaining egg mixture evenly over the top, then top with the cheese so it's evenly covered. Place the olives evenly over the top of the cheese.
Place into the oven and bake at 30-35 minutes, or until the egg is cooked through.
Let it sit for a few minutes before slicing and topping with green onion, avocado, and tomato.
