We did this earlier this week and it was REALLY good - and completely simple, a nice combination.
(adapted from Everyday Food November 2007)
1 can black beans, drained
1 jar mild or medium salsa
2 tablespoons chopped canned chipolte chiles in adobo sauce
1 1/2 pounds boneless, skinless chicken thighs (about 8)
salt and pepper
1 medium red onion, chopped
1 red pepper, chopped
In the slow cooker, stir together beans, salsa, chiles and 1 cup of water. Season chicken with salt and pepper; arrange on top of bean mixture. Toss the onion and pepper on top of the chicken.
Cover and cook on low for 8 hours. Do not open or stir.
Remove chicken from stew and shred into large pieces and return to stew. Serve topped with sour cream and cilantro, if desired.
