Heat a large skillet over medium heat. Add the ground beef and break up. Season with salt and pepper. (Don't miss my section on the post on substitutions and variations for crockpot chili.)

1 pound ground beef,1 1/2 teaspoon salt,1/4 teaspoon black pepper

Add in the green pepper, onion, and garlic. Cook for 4 to 5 minutes, until you can no longer see pink. There is no need to cook the beef all the way through. Drain the fat from the skillet.

1 green bell pepper,2 cloves garlic,1 medium yellow onion

Add the beef mixture to the slow cooker. Add in the chili powder, cumin, ground chipotle, and ground cayenne pepper. Mix in the Worcestershire sauce, liquid smoke, kidney beans, diced tomatoes, and tomato sauce.

2 tablespoons chili powder,1 tablespoon cumin,1/2 teaspoon ground chipotle,1/2 teaspoon cayenne pepper,1 tablespoon Worcestershire sauce,1 tablespoon liquid smoke,14 ounces kidney beans,28 ounces diced tomatoes,15 ounces tomato sauce

Cook on low for 8 to 10 hours or on high for 4 to 5 hours. Serve with diced red onion, corn chips, sliced jalapenos, shredded cheese, sour cream, and fresh cilantro.
