12 slices day old white bread, crust removed
1/2 lb. sliced cheddar cheese
4 eggs
2 1/2 c. milk
1 tsp. mustard
1 tbsp. chopped onion
1 tsp. salt

Arrange 6 slices bread in the bottom of a buttered baking dish. Cover with meat if desired. Place slices of cheese on top of this. Cover with remaining bread slices.

Beat eggs until light and foamy; add milk, mustard, onion, and seasonings. Blend using blender if available. Pour over the bread, saturating all. Refrigerate at least 1 hour-overnight. Bake uncovered in 325 degree oven for 1 hour. Cut into sandwich triangles for serving.
