1 lb. round loaf sourdough bread
1/4 C. balsamic vinegar
1 T. olive oil
1 tsp. dried oregano
1 tsp. dried parsley flakes
1/4 tsp. pepper
2 cloves garlic, minced
1 C. sliced fresh mushrooms
6 (1/4-inch thick) tomato slices

Slice Bread in half horizontally. Remove soft bread from inside each half, leaving 1/2-inch-thick shells; set shells aside. Reserve soft bread for another use. Combine vinegar and next five ingredients in a shallow dish; add mushrooms, tomato and onion. Let stand 15 minutes. Drain, reserving marinade. Brush marinade inside bread shells. Layer half each of zucchini, mushroom mixture, and cheese in bottom half of loaf; top with bologna. Repeat layers; top with turkey and remaining half of loaf. Wrap in plastic wrap; chill. To serve, unwrap loaf; cut into wedges.
