Spicy Cajun vegetable skewers are perfect for those who enjoy a bit of heat. Chop a variety of vegetables such as bell peppers, red onions, cherry tomatoes, and corn on the cob into bite-sized pieces. In a bowl, mix together Cajun seasoning, olive oil, lime juice, and minced garlic. Toss the vegetables in the spicy marinade and let them sit for at least 30 minutes. Thread the vegetables onto skewers and grill over medium-high heat for about 10-15 minutes, turning occasionally, until they are tender and slightly charred. Serve the skewers with a side of creamy ranch dressing or a cooling cucumber yogurt sauce.
