I made a version of this the other night from the Better Homes & Gardens crockpot recipe book.
I used
1 Eckrich skinless smoked sausage (they come in a package of two; original recipe said "polish sausage"), diced in 1/4 to 1/2 inch rounds
2 boneless skinless chicken breasts (I used one really large one)
1 red onion, chopped
1 (16 oz) bag of baby carrots
3 bay leaves
1 tsp garlic
1/2 tsp thyme
1/3 cup red wine vinegar (recipe called for 1/2 cup red wine, but we didn' have any)
1 can of diced tomatoes
1 cup of chicken broth
1 can of black beans, rinsed (the recipe called for white or canneli (sp) beans or kidney beans, but we only had black beans)
Place carrots, onions, and tomatoes in crock pot. Pour in wine (or vinegar), and add garlic & thyme and broth. Stir. Add beans and stir gently. Place chicken on top of mixture. Place sausage on top of chicken. Cover & cook on low for 6 to 8 hours.
Our crockpot sometimes gets "dry" (burns off liquids) and so I added the extra cup of broth listed (recipe did not call for any). It was a little "soupy" on the bottom, but I just used a slotted spoon to get the food out.
It turned out very yummy. It fed 4 people.

Crockpot chicken & dumplings is really good.
