Wash the vegetables well, and cut them into skewer friendly pieces. Marinade the veggies in Smoke on Wheels BBQ Marinade for 2-4 hours, then thread the vegetables onto skewers, alternating colors.
Season to taste with Cattleman’s Grill Tri-Tip seasoning. Preheat grill to medium heat (about 350º), place the skewers on the grill and cook until the vegetables are tender, about 10 minutes, turning occasionally.
TIP: The use of a double prong or flat skewer will make assembling and grilling your kabob a breeze.
