Take a trip to Greece with these delicious Greek-style veggie skewers. Use a combination of vegetables like cherry tomatoes, red onions, bell peppers, zucchini, and halloumi cheese. Marinate the vegetables and halloumi in a mixture of olive oil, lemon juice, garlic, and dried oregano. Thread them onto skewers and grill until the halloumi is golden and the vegetables are tender. Serve these skewers with a side of Greek salad and some warm pita bread.
