Heat oven to 400°F.
Slice Italian bread lengthwise, then cut crosswise into 4 sections, each about 4 inches long.
Spread each piece of bread with pizza sauce, dividing equally. Then top with 1/4 cup cheese and 3 slices of pepperoni.
Bake at 400°F for about 12 minutes or until cheese is melted and lightly browned. Serve immediately.
