1 cup shredded American cheese (or your choice of cheeses)
Heat oil in a large stock pot and cook onions until slightly browned and then stir in the chili powder, tomato paste, garlic, cinnamon, oregano, allspice, 3/4 teaspoon of pepper, and 1 teaspoon of salt.
Cook until fragrant, and then stir in the chicken broth, tomato sauce, vinegar, and sugar.
Crumble raw burger into the chili mixture, bring to a boil, reduce heat and cook on a high simmer until burger is done and the mixture is slightly thickened; salt and pepper to taste.
(While the mixture is cooking, cook spaghetti according to package directions) and heat the beans just too warm.
Serve chili over spaghetti topped with beans and cheese.
