1 loaf French bread
1 pkg. sliced Swiss cheese
1/2 c. butter, softened
1/2 tsp. dry mustard
1 tbsp. minced onion
2 slices bacon

Cut the French bread in to 1 inch slices. Cut cheese slices in half, then cut each half diagonally. Put the cheese pieces between the slices of the bread. Make a foil boat for the bread; wrap tightly around the bottom of bread. Mix the butter, dry mustard and onion together and spread over the top of the bread. Bake at 400 degrees for 8 to 10 minutes or until bacon is crisp. Serve immediately.
