Bison is a healthy, tasty alternative to beef that's perfect for chili. This chili cooks down to a thick, hearty mixture of kidney beans, black beans, and ground bison over the course of two hours, which allows the flavors to fully develop.
Heat the vegetable oil in a large saucepot over medium heat. Cook the garlic and onion together until translucent. Add the bison, increase the heat to high, and continue to sauté until no pink remains in the meat. Add the crushed tomatoes and tomato juice and simmer for 1 hour. Add the remaining ingredients, and continue to simmer for 1 more hour. Adjust seasoning as needed.
