Preheat your oven to 400 degrees. Add the frozen mini tater tots directly into a lightly greased deep pie dish. Spread them in an even layer and bake according to package instructions until fully cooked and crisp.
Remove the dish from the oven and, while the tots are still hot, use the bottom of a glass to lightly press and spread them into a thin, even crust that covers the bottom of the dish. (You an spray the bottom of the glass so it doesn't stock or use the back of a fork to press down gently)
Cook the breakfast sausage in a skillet over medium heat until browned and crumbled, then set aside.
In the same skillet, sauté the diced onion and diced red and green peppers until softened, about 3 to 4 minutes, then set aside to cool slightly.
In a large bowl, whisk the eggs until smooth. Add the cottage cheese, shredded mozzarella, and shredded cheddar and stir to combine. Season with salt and pepper to taste.
Fold in the cooked sausage, onions, and peppers until evenly distributed.
Pour the egg mixture over the tater tot crust, spreading it evenly.
Bake for 30 minutes, or until the top is golden and the center is set. Let it rest a few minutes before slicing and serving.
