Start making your veggie skewers by soaking your wooden skewers for at least 30 minutes. Chop the onion and bell pepper into large chunks and cut squashes into rounds about 1/2 inch thick but leave the mushrooms whole.
Thread all your veggies on each skewer alternating colors and varieties.
Using an Olive Oil Sprayer, spray each veggie skewer with plenty of olive oil. Sprinkle with salt and black pepper.
Place on a hot grill and grill for about 10 minutes
Turn your vegetable kabobs often until lightly charred.
Serve your vegetable skewers as a great side dish for all your cookouts.
