Turn your grill into a panini press with this veggie-packed sammie. (It’s also a great way to use up allll that zucchini.)
Heat a grill or grill pan over medium heat. In a small saucepan, combine the EVOO and garlic and heat on the grill (or on the stovetop over medium heat).
Brush the eggplant and zucchini on both sides with the garlic oil; season with salt, pepper and herbes de Provence. Place on the grill along with the bell peppers and cook, turning once, until crisp-tender, 6 to 8 minutes.
Arrange the vegetables on the bread loaf bottom and top with the cheese and arugula. Spread the bread top with the tapenade and set in place. Place the sandwich on the grill and cover with 2 bricks covered in foil or place in a skillet piled with heavy cans. Press the sandwich until crisp on top, about 2 minutes. Flip and repeat. Cut into 4 portions.
