This is a recipe I adjusted a few years ago and decided to see if it would freeze well a few months ago. It did and we enjoy having it as a "breakfast dinner" on a weeknight like Wednesday when we're running out of the house just after dinner time.
1 lb. breakfast sausage, cooked & crumbled
1/2-3/4 c. chopped green/red peppers & onions (cook with sausage)
3 c. shredded cheddar cheese
4 eggs
1 1/2 c. milk
2 lbs. tater tots - used on serving day
Whisk together the eggs and milk with salt/pepper to taste. Layer in greased 9x13 pan (or 2 8x8s): sausage with peppers & onions, cheese, then egg mixture. Tater tots remain in their original package in the freezer until serving day.
To Freeze: Cover with 1 layer of plastic wrap and 1 layer of foil.
