Heat olive oil in a small frying pan over medium high heat and add chopped onion. Reduce heat to medium and saute the onion, stirring occasionally until softened and transparent for about 3-4 minutes. Add the garlic and saute, stirring, an additional one minute. Remove from the heat.
Place the chicken breasts in the crockpot. Mix the cumin, Mexican oregano, coriander, paprika, cayenne pepper, salt and pepper in a small bowl. Sprinkle the spices evenly over the chicken.
Add beans, green chiles, chicken broth, and onions with garlic and stir. Place cover on the crockpot and cook on low for 5-7 hours or until the chicken is easy to shred.
When chicken is done, remove to a plate and shred it with two forks. Place the chicken back in the crockpot and add 1 cup of frozen corn, 1 cup of Greek yogurt or sour cream (I use Greek yogurt), and the juice of one fresh lime.
Turn crockpot to high and cook another 15 minutes until soup is heated up.
Serve with desired toppings.
