Crockpot Chicken Tortilla Soup

ok, so this soup is inspired by my cold....i love soup when I am sick and I am hoping the extra spice will clear me up. I looked at a bunch of recipes to come up with this one...and the best is if you are sick it can cook all day while you lay around on the couch. I am posting now bc people indicated interest, I have not made this yet and will add pictures later. ***USE CROCKPOT LINERS...U WILL THANK ME LATER...ALMOST NO CLEAN UP!*
 Karen's Crockpot Chicken Tortilla Soup
 1 Tbsp olive oil
 2-3 cloves garlic, minced
1 Jalepeno, chopped (optional, but highly recommended)
 1 (14.5 oz can) black beans, rinsed and drained
 1 (14.5 oz can) small white beans, rinsed and drained
1 C of frozen white corn kernels
 2 cans (14.5 oz) Rotel diced tomatoes with green chilis
 1 packet mild taco seasoning mixabout a tsp of Adobo
2 cans low sodium chicken broth (there is a lot of sodium in the taco seasoning)
3 boneless, skinless thin cut chicken breasts
 juice of a lime
 2 Tbsp fresh cilantro (optional)
 cornstarch slurry (1 tsp cornstarch and 1 Tbsp dry sherry, chicken broth or white wine, mix and add at the end)
1/2 C sour cream (optional)
 Garnishes: Tortilla strips (can find in salad dressing aisle near croutons), shredded cheese, avocado

Saute garlic and jalepeno over medium heat for 1-2 minutes. Place crockpot liner in crock, and put in beans, corn, jalepeno/garlic mixture, diced tomatoes, chicken broth, taco seasoning and adobo. Mix well and add chicken breasts. Cover and cook on low for 5 hours (6 hours if you use regular skinless, boneless chicken breasts instead of thin cut) or high for 3-4 hours. When chicken is cooked through, remove and shred with two forks. Put chicken back in soup, squeeze lime juice in and add cilantro and mix. **I thought the soup was a little thin so I mixed 1 tsp cornstarch and 1 Tbsp dry sherry and put the crock on the keep warm setting for an hour to thicken...can use chicken broth or white wine instead of dry sherry, but the liquid has to be cold when you mix or it wont work). *****today I used a roux (equal parts flour and butter and then add some chicken broth and add and whisk into soup) Shut off crockpot and stir in sour cream. Serve with optional tortilla strips, shredded cheese, avocado.
