In a medium sized bowl, whisk together the chicken broth, chicken bouillon, MSG and cream of mushroom soup. Pour this over the ingredients already in your slow cooker. If you feel you need more liquid, add a bit of water. Cook on low for 4–5 hours, occasionally stirring, until potatoes are cooked through and break apart easily. Careful not to cook too long or they’ll turn to mush. Keep a close eye on the liquid level, adding more if needed.
