Notes
Note: You can't easily drain the fat from the ground beef in this recipe. Consider buying 93% lean beef or brown it in a separate pan.This is a beanless chili. However, if you are a bean lover or maybe you'd like to keep it vegetarian, consider adding a couple of cans of pinto beans, kidney beans, or black beans.Like many chili recipes, this tastes great the next day. Be sure to store any leftovers in an airtight container in the fridge for 4-5 days or freeze it for the future.
