Abstract: A portable cooking grill supported on support elements slidable on a series of rods driven into the ground and clamped thereto with eyebolts. In one embodiment, a rectangular enclosure open at the top and bottom surrounds a grill supported at an intermediate height to create a chimney effect aiding in cooking. The enclosure is assembled from separate panels without separate fasteners, and a top may be added to create an oven. In a second embodiment, two rods have forked clamping bars slidable thereon and clamped at a selected height with the eyebolts.
