In a large skillet, heat oil over medium-high heat. Add onions; cook and stir until tender. Add garlic; cook 1 minute longer.
Transfer to a 3-qt. slow cooker; place chicken breasts on top of onions. Stir in beans, stock, chilies and dry seasonings.
Cook on low for 6-8 hours. Remove chicken breasts and shred with 2 forks. Return chicken to slow cooker. Stir in cilantro. If desired, serve with corn chips, cheese, lime wedges and sour cream.
