Crockpot White Chicken Chili (Keto)

Made this delicious white chicken chili.  My family complained I didn't make enough.  I put cheddar on mine.  It is beanless since it's Keto/low-carb.  You can always add white beans and eliminate the Xantham gum if you aren't concerned about carbs.  You could also use beans and leave out the chicken if you want it vegetarian.  My kids ate theirs with pasta.

Ingredients
1 large yellow onion, diced
3 multi-colored bell peppers, chopped
2 lbs chicken breasts, boneless skinless
4-5 garlic cloves, minced
7oz can green chilies
3 cups chicken broth
2 Tbsp chili powder
2 tsp cumin
2 tsp salt
1 tsp Xantham gum (optional)
10oz bag spinach, roughly chopped
1 1/2 cups sour cream

Directions
Throw all the ingredients in the crockpot except the sour cream.  Cook 4-5 hours on high or 7-8 on low.  Shred chicken and mix in sour cream.
