Greek-style veggie skewers are a refreshing and healthy option. Chop a variety of vegetables such as cherry tomatoes, red onions, bell peppers, and zucchini into bite-sized pieces. In a small bowl, whisk together olive oil, lemon juice, minced garlic, dried oregano, salt, and pepper. Toss the vegetables in the marinade until well coated. Thread the vegetables onto skewers and grill them over medium heat for about 10-15 minutes, or until they are tender and slightly charred. Serve the Greek-style veggie skewers with a side of tzatziki sauce and a sprinkle of crumbled feta cheese for an authentic Greek flavor.
