Preheat your oven to 350°F (175°C).
Spray a 9x13 inch baking dish with cooking spray.
Spread the frozen tater tots evenly across the bottom of the dish.
In a large bowl, whisk together the eggs and milk.
Add salt and pepper, then mix well.
Stir in the cooked sausage or bacon, bell peppers, and onions.
Pour the egg mixture over the tater tots.
Sprinkle shredded cheese on top.
Bake for 30-35 minutes, or until the eggs are set.
Let cool for a few minutes before slicing and serving.
