Using a food processor to make pork and vegetable skewers can help you achieve evenly sized and well-seasoned pieces. Start by cutting pork tenderloin into cubes and marinating them in a mixture of olive oil, lemon juice, minced garlic, and your choice of herbs and spices. While the pork is marinating, use the food processor to chop vegetables such as bell peppers, zucchini, and red onions into bite-sized pieces. Thread the marinated pork and chopped vegetables onto skewers, alternating between the different ingredients. Grill the skewers over medium-high heat, turning occasionally, until the pork is cooked through and the vegetables are tender. Serve the pork and vegetable skewers with a side of rice or a fresh salad for a delicious and colorful meal.
