Stir everything except the cornstarch (or flour), water (or broth) and butter into a 1.5-quart (or larger) slow cooker. Place cornstarch (or flour) in a bowl and slowly whisk in the water (or broth), stirring to prevent lumps. Pour over the vegetable mix. Add the butter, then cover slow cooker and cook for 6 hours on high.
