Summer-Veggie Melts with Caper Sauce
A colorful mix of grilled vegetables—bell peppers, onion, and Broccolini—is packed into a hoagie that gets a toasty crust on the grill but stays pillowy-soft in the center. Provolone, the perfect melting cheese, melds it all together. The final touch to take this vegetarian sandwich masterpiece over the top is a generous smear of a zesty basil-caper aioli.
