Pork and vegetable skewers are a delicious and healthy option for a simple dinner. Start by cutting pork tenderloin into cubes and marinating them in a mixture of olive oil, garlic, lemon juice, and herbs. Meanwhile, prepare your choice of vegetables such as bell peppers, onions, and zucchini by cutting them into bite-sized pieces. Thread the marinated pork and vegetables onto skewers and grill them until the pork is cooked through and the vegetables are tender. Serve the skewers with a side of rice or a fresh salad for a complete meal.
