Mexican-style veggie skewers are a vibrant and flavorful option inspired by Mexican cuisine. Chop a variety of vegetables such as bell peppers, red onions, zucchini, and corn on the cob into bite-sized pieces. In a bowl, mix together olive oil, lime juice, minced garlic, chili powder, cumin, paprika, salt, and pepper. Toss the vegetables in the Mexican 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 guacamole, salsa, and warm tortillas.
