How to Make It
Heat a large nonstick skillet over medium-high. Add beef to pan; cook, stirring often, just until crumbled and mostly browned, about 3 minutes. (Beef will not be fully cooked.) Remove from heat.
Combine sweet potatoes and next 11 ingredients (through black beans) in a 6-quart slow cooker. Stir in beef. Cover and cook on LOW 7 hours. Stir in 1/2 cup cilantro. Ladle chili into 8 bowls; top with cheese and remaining cilantro.
