1 1/2 c. thinly sliced fresh mushrooms
1 c. seeded and chopped cucumber
2 Tbsp. sliced green onions
2 cloves garlic, minced
1/4 c. balsamic vinegar
1/4 tsp. freshly ground pepper
2 (2 oz.) hoagie buns
4 lettuce leaves
4 oz. thinly sliced lean ham
4 oz. thinly sliced turkey breast
8 slices tomato
1/2 c. (2 oz.) shredded part-skim Mozzarella cheese

Combine first 6 ingredients; let stand 30 minutes. Slice buns in half horizontally. Pull out soft inside of both top and bottom halves, leaving 1/2-inch thick shells (reserve crumbs for other uses). Line each bottom half with a lettuce leaf. Spoon mushroom mixture evenly onto lettuce, using a slotted spoon. Cover with remaining lettuce. Arrange ham, turkey, tomato slices and cheese on lettuce. Place top halves on sandwiches; wrap in plastic wrap. Chill up to 2 hours. Cut in half to serve. Yields 4 servings.
