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 small bowl, mix together Cajun seasoning, paprika, garlic powder, onion powder, salt, and cayenne pepper. Toss the vegetables with olive oil and the Cajun spice mixture until well coated. Thread the vegetables onto skewers and grill them over medium-high heat for about 10-15 minutes, or until they are tender and slightly charred. Serve the spicy Cajun vegetable skewers with a side of creamy ranch dressing for dipping.
