- Heat the grill or a grill pan to medium high. Arrange the zucchini, squash, bell peppers, and onion on a rimmed baking sheet. Whisk the vinegar and olive oil together in a bowl to blend. Brush the cut side of each roll with a small amount of the dressing mixture, then toss the vegetables with the remaining dressing. Season with salt and pepper. Grill the cut side of the rolls until toasted, about 1 minute. Place the rolls cut side up on plates.
- Grill the veggies until tender and lightly charred, turning and brushing occasionally with any dressing mixture left on the baking sheet, about 10 minutes.
- Spread the bottom half of each roll with 1 1/2 tbls. tapenade, and top with warm vegetables. Cover the veggies in each sandwich with 2 slices of cheese, and a quarter of the banana peppers and basil. Finish with an additional drizzle of olive oil and a pinch of salt and pepper.
- Cover each sandwich with the top of roll, and press down gently to marry the flavors. Enjoy!
