Here is how Bob grills veggies on the barbeque.  (I had him describe the whole process to me.)  They are yummy!!

You will need any desired combination of vegetables, this time we used red potatoes, zucchini, broccoli, red and green peppers, red onion

Preheat barbeque on low, about 350 degrees.  Lay down a large piece of heavy duty foil and put your barbeque basket or grill tray or whatever on top and spray with Pam or brush with olive oil.  Layer veggies on top, starting with red potatoes, zucchini, broccoli, red and green peppers, ending with red onion.  Sprinkle with salt and pepper or any other desired seasonings (can be sprinkled between layers as well).  Put grill basket directly on barbeque rack and let cook for 10 – 15 minutes, watching potatoes to make sure they don’t burn.  Then transfer all veggies to another large piece of heavy duty aluminum foil, wrapping them up like a burrito.  Place burrito on top shelf of barbeque and cook for about 20 – 25 more minutes or until veggies are tender.
