One crockpot recipe that my DH loves so I make it at least every other month or so is Black bean soup:

1 pound of chicken tenders (I throw them in frozen)
2 cans of rinsed black beans (although I use soaked ones)
2 cups of sliced mushrooms
1 can of chicken broth
1 tbls of cumin
2 -4 cloves of garlic, minced
1 jar of chunky salsa (I use Hot)

Right before serving stir in either 1 cup of sour creme or I use nonfat plain Greek yogurt.

Garnish with cheddar cheese and a slice of avocado.

Your house will smell great while this is cooking and it freezes well too.
