Super easy. Break down bird(s). Chop up an onion, you can add carrot &/or celery if you have them. Open a can of those seasoned diced tomatoes - the 19oz size, use 2 if you've slayed lots of chickens. Throw it all in a pot, you can add a little water if you think the grouse isn't covered enough, cover and simmer for 30-40 minutes, longer if you're enjoy pops and not rushed. Tender stuff. Also the same base ingredients can be used for all sorts of other meats, even made caribou heart soup with it.
