Then add your tater tots and put them in a single layer as best you can and sprinkle the chopped bacon on top.
In a large bowl whisk up your eggs. Add in your milk, sliced green onions, salt, ground mustard, and shredded cheese. Mix it all together.
Pour the egg mixture over the top of your meat and tater tots. With a spatula help spread your cheese around to make sure it is even all over the top of your casserole.
Bake in a 375 degree oven for 50-55 minutes.
