Stuffed Bread

1  loaf  Vienna bread, unsliced
8  oz  Swiss cheese, sliced
1-1/2  sticks  butter or margarine, melted
2  Tbs  poppy seeds
1  tsp  seasoned salt
1  tsp  prepared mustard
1/2  tsp  garlic salt
1  Tbs  onion, chopped
2  small  cans  sliced mushrooms

Cut bread diagonally one way, being careful not to cut all the way through the bottom. Now cut the other way, creating a criss-cross pattern. Place on heavy foil, large enough to cover loaf completely.

Add the poppy seeds, seasoned salt, mustard, garlic salt, and onion to the melted butter.

Stuff cheese and mushrooms into the diagonal slices of bread. Drizzle the butter mixture over the top. Wrap completely with foil. Bake @350 degrees for about 30 minutes or longer.
