Greek halloumi and vegetable skewers are a delightful combination of flavors. Cut halloumi cheese into cubes and marinate them in a mixture of olive oil, lemon juice, garlic, and dried oregano. Thread the cheese cubes onto skewers along with colorful bell peppers, cherry tomatoes, red onions, and zucchini. Grill the skewers until the halloumi is golden brown and the veggies are tender. Serve them with a side of tzatziki sauce and warm pita bread for a taste of Greece.
