We've been doing a fair amount of reading in the area of Solar Grills. A solar grill is the perfect addition to your outdoor kitchen and can barbecue fish, chicken, GIANT steaks, and yes - even vegetables. The Solar-Grill has a flexible mirror, which focuses the sun beams on the barbecue cup allowing it to heat up. Your meal is cooked in the self contained barbecue cup an heated evenly from all sides, without direct irradiation by sunlight.

Update:The Tammock site now has an order form for those who want to purchase their own solar grill.
I knew I was missing something in my Outdoor Kitchen - a mud oven! Not only are mud ovens easy to create, they make a great way to create pizzas, loaves of bread, and perhaps a giant roasted leg of lamb in your back yard. You'll need some sand, clay and other items to create one. Get the details at Handy Home Projects.
