Our guide to the best grilled vegetables will keep you fired up all summer long. Just pick your veggie -- or make mix-and-match kebabs -- and master a few basic techniques.

Finally, if you'd like to add restaurant-worthy crosshatch marks, wait until the grate leaves a set of lines, then rotate the vegetables 90 degrees. It's surefire advice for mouthwatering success.
