Heat oil in large saucepan over medium-high heat. Add ground chicken, sausage and 1 teaspoon chili powder; cook 5 to 7 minutes or until chicken is no longer pink. Remove meat mixture from saucepan; set aside.
Add onion, pepper and garlic; cook 5 minutes or until tender, stirring occasionally. Add cumin, paprika, salt and remaining 1 teaspoon chili powder; cook 1 to 2 minutes more or until spices are fragrant.
Return cooked meat mixture to saucepan; stir in crushed tomatoes, beans and undrained tomatoes. Bring to a boil. Reduce heat and simmer 10 minutes or until mixture is hot. Top each serving with sour cream and parsley, if desired.
