Do you mean like a frozen egg casserole or breakfast foods with eggs in them? If you are thinking of some type of casserole read the link below (for some reason it didn't want to be added right here!)
Eggs (like scrambled) when frozen alone tend to get rubbery, but when cooked into things they do fine. I freeze whole grain muffins and pancakes all the time and they taste fine. Maybe not 100%, like my muffins tend to be a bit more crumbly and the pancakes aren't quite as fluffy. However the texture and taste are fine and neither my kids or myself mind the minor differences.
Freezer cooking is a awesome way to make life easier. Like anything else it takes some trial and error and you need to find recipes that you and your kids will eat. www.ehow.com/how_7266824_freeze-egg-casser
