This classic Mexican sandwich, or torta, swaps the usual meat for colorful grilled summer vegetables. The traditional black bean spread adds protein and acts as a moisture barrier so the bread stays extra crispy.
Cut bell pepper in half lengthwise; discard seeds and membranes. Place pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil 11 minutes or until blackened. Wrap pepper halves in foil. Let stand 5 minutes; peel. Cut into strips.

Place juice, oregano, oil, cumin, 1/4 teaspoon black pepper, ground red pepper, and beans in the bowl of a food processor; pulse 5 times or until coarsely chopped.
Step 4

Step 5
Hollow out top and bottom halves of bread. Leavie 1-inch-thick shell. Spread black bean mixture over bottom half of bread. Top with zucchini, onion, and bell pepper. Sprinkle with remaining 1/4 teaspoon black pepper, salt, and cheese. Top with top half of bread. Coat both sides of sandwich with cooking spray. Place sandwich on grill pan and top with a heavy skillet. Grill 3 minutes on each side or until cheese melts. Remove sandwich from pan and cut into quarters.
