Add the ground beef, dry pinto beans, tomatoes, corn, diced bell pepper, diced onion and minced garlic to the slow cooker.
Warm the water in the microwave. Mix the beef bouillon cubes into the water until dissolved. Pour into the slow cooker and mix until combined with the ingredients.
Add the tomato paste, cocoa powder, chili powder, cumin, onion powder, salt and pepper. Mix well, ensuring the liquid fully covers the pinto beans.
Cook on LOW for 7 hours. Change to HIGH for an additional hour, to cook for a total of at least 8 hours.
When finished, stir in the red wine vinegar.
Serve warm, topped with shredded cheddar cheese, fresh cilantro, jalapeños or sour cream if desired.
Notes
Storing: Store chili in the fridge for up to 5 days. It is freezer-friendly for up to 6 months. Thaw overnight in the fridge or quick thaw in microwave or on the stovetop.Tip 1: Canned pinto beans (or a combination of pinto and kidney beans) can be used. Add them during the last hour of cooking. Substitute 8 ounces of dried pinto beans with 2 cans of beans.Tip 2: Chili becomes even more flavorful and delicious as it sits. If you can cook it ahead of time, you wont regret it!
