Most recipes on grilling vegetables don't go beyond washing, trimming and placing them on the grill.. is it that simple? errr.. yes!!! but maybe no.
Though grilling gives vegetables a smoky flavor, the spice lover in me feels it can be tastier. So what I like to do is marinate most veggies in a light marinade. Earlier, we used to just marinate veggies in the Italian dressing....which really works beautifully but now I just throw together some spices and olive oil and that's it. The proportions keep changing.. more garlic sometimes, some paprika sometimes, some cumin...play with it.
Most veggies do well on the grill, but some really stand out--asparagus, corn, eggplant, mushrooms, peppers (bell or hot), onions, cauliflower. Most vegetables cook better and are less likely to stick if marinated first or brushed lightly with cooking oil just before grilling. For added flavor, sprinkle grilled vegetables with fresh herbs.
To avoid scorching or overcooking, you want the grill fire to be medium-hot.(Test the temperature by
holding your hand 5 inches above the grill grate; if you can hold your hand there for only three to four seconds, the fire is medium-hot.)To grill, place vegetables on a piece of heavy foil or on the grill rack directly over the preheated coals. If putting them directly on the grill rack, oil the rack and lay them perpendicular to the wires of the rack so they won't fall into the grill. Grill, uncovered, for time in chart or till tender, turning occasionally. Watch closely to prevent charring. Direct heat works best so I alternate between placing them on the foil and then on direct heat.
