White Bean TOFU Chili

I got this recipe from my friend Amanda. It's very tasty! I assume that it would be easy to substitute tofu or something for the chicken. I've used fish instead of chicken and it turned out fine. I love recipes that only have one step!

Ingredients
1.25 pounds chicken tofu
2 cups chicken vegetable broth
11 oz can white corn, drained
2 12 oz cans Great Northern Beans, drained
1/2 cup fat free sour cream
1 small white onion, chopped
4 oz can green chiles, chopped
14 oz can diced tomatoes, drained
1/2 tsp garlic powder
1 packet White Bean Chili Seasoning mix (not gluten free) OR 1-2 tbsp chili seasoning (gluten free)

Directions
Combine in large pot on medium heat for 1 hour, stirring occasionally.
