Fire up the grill for this mouthwatering veggie sandwich. Slice zucchini, bell peppers, and eggplant, then brush them with olive oil and sprinkle with salt and pepper. Grill the vegetables until tender and slightly charred. Assemble the sandwich by layering the grilled veggies on whole wheat bread with some melted mozzarella cheese. Press the sandwich in a panini press until the cheese is melted and the bread is crispy. This grilled vegetable panini is a perfect combination of flavors and textures.
