Do your grilling this Memorial Day weekend in a way that's fast, clean and green, too. Put one small, tightly-packed cube of recycled wood inside the Woodflame Delecto Grill's oxygen-filled combustion chamber, and it's ready to start cooking in less than two minutes. When you're done, all that's left is a pinch of ash. Sounds pretty efficient. Better be for $250.
