Preheat the oven to 425 degrees. Grease a 9.5-inch pie plate with nonstick cooking spray.
In a large bowl, beat the eggs. Stir in the cheese, chiles, pepper, green onions, and cumin. Season to taste with salt and pepper. (The dish can be refrigerated or frozen at this point, if desired. Thaw before baking.)
Bake the egg dish for 15-20 minutes or until set. Serve immediately.
Store leftovers covered in the fridge for up to 4 days.
