On the Fourth of July, Americans love to light it up. On the grill, that is. Most do hotdogs, burgers and steaks, but you can do a lot more. Our grill gal, Gretchen McKay, and videographer Steve Mellon continue their series of videos on how to grill some different recipes -- for the Fourth and all season long. All are easy to make, healthful, and a great way to get you out of a hot kitchen.

This week Gretchen grills asparagus with orange and parsley, and makes portobello mushroom burgers.
