Well, I have a fish pond in my garden. One of the koi died a few years ago and I put the carcass in the compost bin. The fish probably weighed about 2 lbs or more. The compost was heating up fairly well, up to 150F or more, and when I turned the compost a few days later there was a wonderful aroma of tender flakey baked fish! Of course I didn't even think of eating it (the fish are like pets, and I wouldn't eat anything out of a compost pile anyway) but this is an example of unusual cooking methods... lol...
