Grill the kabobs over a medium-hot fire, with the lid closed, for 8 to 10 minutes. Turn the kabobs, close the lid and cook until the vegetables are just slightly soft, about 5 minutes.

It gives the vegetable more surface area to crisp up and turn a lovely golden brown color. The best way to do this is to simmer or steam them first, then fry them in a liberal amount of oil.
