Layer bread in 9x13 casserole dish
Sprinkle with 1/2 of the grated cheese
Beat eggs with milk & salt and pour half over cheese in dish
Do 2nd layer -- cheese, then remaining eggs
Leave in refrigerator overnight
Bake 350 F for about 45 minutes.
Good idea to put cookie sheet under casserole dish to catch any that spills over while baking.
