In a large pot, heat the olive oil over medium heat.
Add any additional vegetables you’d like, such as diced onion, bell pepper, or garlic, and sauté for about 5 minutes until softened.
Stir in the cumin, chili powder, and onion powder, cooking for an additional minute until fragrant.
Add the cooked chicken, white beans, diced tomatoes, corn, and chicken broth to the pot, stirring to combine.
Bring the mixture to a simmer, then reduce the heat and cover the pot, letting it cook for 15-20 minutes.
Taste and season with salt and pepper as needed, adjusting the spices according to your preference.
Serve hot, topped with Greek yogurt or sour cream and additional toppings of your choice, like cilantro or jalapeños.
