1 loaf French or Italian bread
1/4 lb. butter
2 tsp. Dijon mustard
1 med. onion (chopped fine)
2 tbsp. poppy seeds
2 tbsp. lemon juice
1 c. Monterey Jack cheese (cubed)

Combine last five ingredients in saucepan and simmer until onions are soft. (Monterey Jack cheese can be omitted. Do not put in saucepan with butter.) Slice bread into one inch thick slices. Spoon butter mixture onto each slice and add cheese if desired. Wrap in foil and leave top exposed. Can be done early in the day, if you refrigerate. Bake at 350 degrees for 20 minutes.
