from Faye:

White bread about 1 loaf cut off crusts,
Line greased baking dish with 1 layer of bread,
Then one layer of cheese slices,
1 layer of ham,
Then layer of bread to top off.
Mix 4 eggs and 3 cups of milk, add teaspoon of mustard any kind
Pour over layers and cover (you might need more milk) leave overnight or a few hours.
Bake at 350 for about 1 hour.
It will rise beautifully like a soufflé. Needs to be served straight away or will go flat. This is so simple everyone usually likes it.
I use any cheese or ham depending on what I have.
I usually use the package ones as they are square like the bread.
