Camp cooking _ A couple of bricks 18" apart with the rack from an old oven or barbeque set on top & you have a grill. You can use wood underneath or even briquets. I have even seen this kind of setup using sterno fuel. So maybe you even have a woodstove in your house and can cook on that, I have used my own woodstove for that purpose. That kills two birds with one stone, heat & cooking. You can even move it outside if you need to use it for cooking during the hot months.
