Here’s a quick (20 minute) Mustard Bread for 6+ people.
1 loaf (soft) Italian bread
1 (8 slice) package "REAL" Swiss cheese
8 ounces favorite mustard
1/2 cup (1 stick) real butter
Melt butter over low flame in a 1 cup Pyrex measuring cup. Just before it boils, squeeze in mustard to fill measuring cup. Stir vigorously while the butter cools and blends in smoothly.
Slice Italian bread into 10 to 12 (1-inch thick) pieces, but not completely through. Liberally brush each side of the sliced bread with 2 strokes of the mustard. Cut package of Swiss cheese in half and slide a piece between each slice of bread. Cover in foil and bake for 15 to 20 minutes or until the cheese gets soft. If you like bacon, top with 6 uncooked bacon slices before cooking.
