In a large pot, heat olive oil over medium heat. Add the diced chicken and cook until browned and cooked through, about 5-7 minutes. Remove the chicken from the pot and set aside.
In the same pot, add chopped onion, garlic, green bell pepper, and jalapeño. Sauté for about 5 minutes, or until the vegetables are tender.
Return the cooked chicken to the pot. Add the chicken broth, white beans, corn, Cajun seasoning, and cumin. Stir to combine all the ingredients well.
Bring the chili to a simmer and let it cook for 15-20 minutes, allowing the flavors to meld together. If the chili is too thick, add more chicken broth to reach your desired consistency.
Season with salt and pepper to taste. Remove from heat and stir in sour cream for creaminess.
Serve the chili hot, garnished with fresh cilantro and lime wedges on the side for a zesty touch.
Notes
Adjust the spiciness by adding more or less jalapeño.
