But "volumizing" your meals isn't simply about piling veggies next to a serving of lasagna or throwing extra tomatoslices or lettuce leaves on your cheeseburger.

Anyone who has grilled a cherry tomato, roasted an ear of corn, sampled eggplant slices brushed with olive oil and cooked over an open flame or even broiled a simple mushroom cap can testify to the joys of grilling vegetables.
