Asparagus falls into the realm of vegetables that lose their nutrients the longer they're cooked. Grilling is a great way to add flavor to asparagus while retaining its nutritional value. And it's super easy! Just toss the stems in olive oil, wrap them in foil, and put them on the grill for about 30 minutes. Sprinkle with a little cheese and some fresh black pepper, and voila -- a tasty and healthy side dish. And you thought asparagus was best in the steamer.
