Preheat oven to 350 degrees F
In a 10-inch cast-iron skillet add the pork breakfast sausage, green pepper, and onion cook over medium heat until the meat is browned and the vegetables soft.
In a medium bowl or a glass measuring cup add the eggs, milk, and cheese, mix until well blended. Pour the egg mixture over the browned meat.
Top the egg mixture with the frozen tater tots and sprinkle with the remaining cheese.
Place in the preheated oven and bake for 35 to 40 minutes until the eggs are set, the tater tots are slightly browned, and the cheese is melted.
Remove from the oven and serve.
