Egg bake. It freezes well, just portion it out. To reheat, we warm it up in the microwave ar about 50% power.
In a 9 X 13 pan dump in a bag of hashbrowns, the aldi bag is the perfect size, I want to say 22 oz. Add in whatever meat and veggies you prefer. We do 1/2 to 1 lb browned sausage,1/4 diced onion,1/4 diced green pepper quite often.
Wisk up 14 eggs, SIL has added in chicken stock in lieu of milk and it worked just fine, but you can use just eggs. Add in salt, pepper and any other seasonings you want. Italian seasonings, basil, thyme, etc are good, so is dry mustard. Pour over the hashbrowns mixture.
Bake 45 min to 1 hour. Until firm (ccheck with a knife)
