It is best to start the night before, have another crock pot. This takes all day. Works with any meat, too.

After dinner, take a Boston Butt roast, place it in the crock pot and let it cook in its own juices, It should be done in the morning. When done, drain the juices and simmer the veggies in the juices in a second crock pot while you place the roast back in first pot with water and gravy mix to cook apart to tenderize.

Should be ready by lunch time, when done, drain veggies, add to meat and simmer till dinner, serve in crock.
