This recipe is from an Anonymous Griller.

1 green, red and yellow pepper
1 pint cherry tomatoes
2 medium zucchinis
1 medium eggplant
1 small red onion
2 cups Italian salad dressing
2-3 cloves garlic, minced

Soak approximately 15 bamboo skewers in water. Mix together minced garlic and salad dressing set aside. Cut all the vegetables in 2" chunks and soak in pan with dressing and garlic. Let skewers and vegetables soak for 1/2 hour. Put the veggies on the skewers and barbecue for approx. 15 minutes, turning frequently to avoid burning. They will be done when they have grill marks and appear to be steaming. While turning, brush with marinade leftovers. These are extremely delicious and it was easy to add meat to the kabobs for the non-vegetarians in my family.
