This casserole is called 'reunion' as it is served nearly every time at my husband's family reunion.
Reunion Breakfast Casserole
8 - 10 slices bread, cubed (I used to use store bought Italian bread - now I use my own homemade)
1 pound more or less of a mixture of cooked meats you like (we use bacon, sausage, and ham)
6 eggs
3 cups milk
1 cup shredded Mexican blend cheese
1/2 - 1 teaspoon salt (keep in mind the meats already have salt in them)
1 teaspoon dry mustard
1 cup shreddd Italian blend cheese
Put bread in bottom of 9" x 13" baking dish. Mix milk and eggs, add meat and Mexican cheeses, salt and dry mustard.
Pour over bread.
Careful to pour the meats evenly over the bread. Press bread down to get it wet.
Bake covered for 45 minutes. Uncover, sprinkle with Italian cheeses and bake 15 -20 minutes more until it is set and there is no liquid. (I have also poked it with a knife and tilted the dish to let the liquids run to the hot sides to cook.)
It will look puffy like a souffle and 'fall' as it sits. Let sit for 10 minutes. Serve.
