Pork and vegetable skewers are a fun and flavorful option for grilling. Cut pork loin into cubes and marinate it in a mixture of olive oil, lemon juice, garlic, and herbs. Thread the pork onto skewers, alternating with your choice of vegetables, such as bell peppers, onions, and zucchini. Grill the skewers over medium-high heat until the pork is cooked through and the vegetables are tender. Serve with a side of rice or a fresh salad.
