Prepare barbecue grill for direct cooking.
Cut zucchini lengthwise into 1/4-inch slices; lightly spray with cooking spray. Set aside.
Grill poblano and bell peppers, skin-side down, over hot coals until blackened. Place in paper bag and seal. Steam 5 minutes. Remove skin. Grill zucchini and corn, covered, over medium coals, 1 to 3 minutes on each side or until tender and lightly browned. Cut zucchini and peppers into bite-size pieces. Cut corn off cob.
Combine zucchini, peppers, corn, lime juice, black pepper, and jalapeño, if desired, in medium bowl.
Lightly spray one side of tortillas with cooking spray; grill about 30 seconds to 1 minute or until crisp and lightly browned. Spread 1 tablespoon pesto evenly over one side of each tortilla. Top with 1/4 of beans, 1/4 of vegetable mixture, and 1/4 of cheese. Grill, covered, over medium coals until warm (if fire is too hot, protect bottom of tortillas with foil). Top with tomato; serve immediately.
*Note: Jalapeño peppers can sting and irritate the skin, so wear rubber gloves when handling peppers and do not touch your eyes.
