When I was a school cook, the students loved my chili because they thought it didn't have beans in it. They didn't know I puree the beans, tomatoes, onions and green pepper to create a tasty, vitamin-packed chili! —Mary Selner, Green Bay, Wisconsin
In a blender, combine the tomatoes, beans, onion and green pepper; cover and puree until smooth.
In a large saucepan, cook beef over medium heat until no longer pink; drain. Add seasonings and pureed vegetables. Bring to a boil. Reduce heat; cover and simmer for 1 hour. Serve with spaghetti if desired.
