Prepare the Ingredients: Chop the onion, bell peppers, and jalapeño. Mince the garlic. Shred the cooked chicken if not already done.
Sauté the Vegetables: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion, green and red bell peppers, and jalapeño (if using). Sauté for about 5-7 minutes, until the vegetables are softened.
Add Garlic and Spices: Add the minced garlic, ground cumin, chili powder, dried oregano, and smoked paprika to the pot. Stir well and cook for another 1-2 minutes until fragrant.
Add Chicken, Corn, and Beans: Stir in the shredded chicken, corn kernels, and white beans. Mix everything together.
Pour in the Broth: Pour in the chicken broth and bring the mixture to a boil. Reduce the heat and let it simmer for about 20 minutes, allowing the flavors to meld together.
Add Creaminess: Stir in the sour cream or Greek yogurt until fully incorporated. Season with salt and pepper to taste.
Serve: Ladle the chili into bowls and garnish with fresh cilantro. Serve with lime wedges on the side for an extra burst of flavor.
