From The Skinnytaste Cookbook. Enjoy a healthy bowl of Skinnytaste's Slow Cooker Chicken Enchilada Soup. Serve with taco toppings, like sour cream, avocadol, and hot sauce.
In a medium nonstick sillet, heat the oil over medium heat. Add the onion and garlic and cook, stirring until soft, about 3 minutes. Add to the slow-cooker along with the broth, tomato sauce, chipotle in adobo, cilantro, beans, tomatoes, corn, cumin, and oregano.
Add the chicken breasts. Cover and cook on low for 4 to 6 hours.
Remove the chicken, shred it with two forks, and return it to the slow cooker.
To serve, ladle into serving bowls and dividing evenly. Top with cheddar cheese, scallions, cilantro, avocado, and sour cream (if using).
