In a large saucepan over medium-high heat, brown meat until no longer pink. Add onions and continue cooking until softened, 2-3 minutes. Drain juices. Add the remaining ingredients and stir well to mix. Bring to a boil, then reduce heat to low and simmer for 15 minutes. Add water or beef broth if a thinner chili is desired. Serve with warmed or toasted whole wheat bread.
