Due to diet restrictions, I tried making sandwiches without meat. This sandwich turned out to be one of my favorites.


  • 8 onion slices (1/4 inch thick)
  • 1/4 cup olive oil
  • 1/4 cup red wine vinegar
  • 4 teaspoons chopped fresh oregano or 1 teaspoon dried oregano
  • 2 garlic cloves, minced
  • 4 jars (7 ounces each) roasted red peppers, drained
  • 1 loaf (1 pound) French bread
  • 1 cup shredded part-skim mozzarella cheese


  1. Place onion slices in a 13x9-in. baking pan. In a small bowl, whisk the oil, vinegar, oregano and garlic; brush half over the onions. Set remaining dressing aside.
  2. Bake onions, uncovered, at 375° for 10 minutes or until tender. Add red peppers; bake 10 minutes longer or until heated through. Meanwhile, slice bread in half lengthwise, then cut into fourths. Carefully hollow out bottom of loaf, leaving 1/2-in. shells (discard removed bread or save for another use).
  3. Place bread, cut side up, on a baking sheet. Broil 4 in. from the heat for 1 minute or until toasted. Layer with onions, red peppers and cheese on bottom halves of bread. Drizzle with remaining dressing. Broil 4 in. from the heat for 4 minutes or until cheese is melted. Top with remaining bread.
