Balsamic makes a tasty difference when it comes to grilled vegetables. The blend of sweet and tart balsamic complements almost any grilled vegetable for a unique taste that will get your kids eating. Toss the vegetables in a marinade of balsamic vinegar, garlic, and olive oil before grilling. You can grill eggplant, zucchini, red peppers, red onions, cherry tomatoes, and whatever else your family enjoys. Serve the vegetables with pasta and mozzarella balls.
