Spray a square 8" pan or casserole dish with non-stick spray. Preheat your oven to 350 degrees.
Spread half of the grated cheese in the bottom of the prepared baking dish. Arrange the diced chile peppers on the cheese. Sprinkle the remaining cheese over the peppers.
Sprinkle with the salt and pepper. Whisk together the eggs in a small bowl. Pour egg mixture over the top of the casserole.
Bake in the preheated oven at 350° for 35-40 minutes, or until the top is golden brown and the eggs in the middle are set. (Internal temperature should be 160-165°.)
If desired, garnish with sour cream, green onions, and pico de gallo.
