If you're looking for a warm and toasty veggie sandwich, try a grilled veggie panini. Start by grilling or sautéing your favorite vegetables like zucchini, eggplant, bell peppers, and onions. Then, assemble your sandwich with the grilled veggies, some melted cheese, and a spread of pesto or sun-dried tomato aioli. Grill the sandwich until the bread is crispy and the cheese is melted. This panini is a delicious and satisfying option for a quick and easy dinner.
