Ham and Cheese Strata

12 slices bread
6 ham slices
6 cheddar slices
6 beaten eggs
3 cups milk
1 TBS finely chopped onion
1/2 tsp dry mustard
salt and pepper

In a greased 9x13 dish, layer 6 ham and cheese "sandwiches". Combine eggs, milk, onion, dry mustard, salt and pepper; whisk well. Pour liquid over the sandwiches. Cover and refrigerate overnight.
In the morning, remove cover and bake at 300* for 1 hour. Allow casserole to set for 10 minutes before cutting sandwiches in half to serve.

Note: I have also assembled this recipe like bread pudding. In that case, the bread is torn, the ham is chopped and the cheese is grated. This variation is great for older bread.
