Hi, would anyone have any tried and true breakfast casserole recipes they could share? I have a catering for a breakfast for 250 people. They want 2 different kinds of breakfast casseroles, one with meat (I'm thinking sausage and potato) and one heavy with vegetables. I prefer ones that could be assembled a day ahead and baked of the morning of. I don't have much time to test the recipes as I just got the job last night and it is a week away. Thanks to anyone who can help.
