Came up with this one trying to emulate a soup I had at Chilis once. Not sure how close it is since they seem to have it when I go there anymore.
1 can cream of mushroom soup
1 can chicken broth
1 can sliced mushrooms
1 boneless chicken breast
Cut chicken into 1" cubes & brown. Combine all ingredients in slowcooker and cook on low. Scale up for larger pots of soup.
