This is a SUPER easy make-ahead meal. Layer in a crock pot in the following order:
1 can black beans, drained
3 chicken breasts
1 pkg taco seasoning (1-2 Tbsp)
1 can diced tomatoes with green chilies
Cook on high 3-4 hours or low 6- 8 hours. Before serving, add about 1/2 cup instant rice, let it sit 5 minutes. Shred chicken. Serve in tortillas topped with cheese and sour cream. Yum!
