Put a small amount of oil or butter in bottom of coffee cans. Peel potatoes, carrots and onions. Cut into chunks and put into coffee cans. Add the meat, seasonings and a little more oil or butter. Cover tightly with foil. Set in coals to bake for about 1 hour or until meat is no longer pink and the vegetables are tender. Serve with fresh crusty buttered bread.
You can also make this without meat, or with fish or chicken, and any seasonings you desire. Experiment! This is also something you can make ahead of time. Refrigerate and/or keep in cooler until time for use.
