This unusual way to serve chili--over spaghetti--is a solid-gold
tradition in the Queen City. Coat a large Dutch oven with cooking
spray; place over medium-high heat until hot. Add 2 cups onion and
next 3 ingredients; cook until meat is browned, stirr To serve,
arrange spaghetti on individual serving plates. Spoon chili over
spaghetti; top with cheese and remaining 1-1/2 cups onion. Serve with
crackers.
