1. Optional step: Crush the tomatoes with their juice in a blender and set aside.
2. Brown the beef, sausage, and onion in a large pot over medium-high heat. Drain the fat. Add the vinegar and cook for 1 minute to reduce the liquid. Add the tomatoes, tomato juice, beans, chili powder, brown sugar, cayenne, salt, and paprika. Decrease the heat and simmer for 1 hour.
3. Serve in bowls and top with a sprinkle of cheese and 1 teaspoon of sour cream if desired.
Serve with Cinnamon Rolls, corn bread or biscuits and a salad. (Steve's favorite way to eat chili is with a square of Buttermilk Corn Bread in the bowl and the
chili ladled over and then topped with a sprinkling of pepper Jack or Cheddar cheese and a dollop of sour cream.)
Can be made Meatless: Omit the meats and double the beans.
