Preheat your oven to 375°F (190°C).

Evenly spread the frozen tater tots across the bottom of a greased 9x13 inch baking dish.

In a mixing bowl, combine breakfast sausage, bacon, and green onions until evenly distributed.

Spread the sausage and bacon mixture over the tater tots evenly.

Whisk together eggs, milk, salt, and pepper in a bowl until well combined, then pour over the layers in the baking dish.

Generously sprinkle shredded cheddar and Monterey Jack cheese on top.

Bake for 40-45 minutes until the eggs are set and the cheese is bubbly and golden brown.

Let the casserole rest for 10 minutes before cutting into squares and serving warm.
