Heat a nonstick skillet over medium- high heat and add ground beef. Break beef down with a wooden spoon as it browns until half cooked. Add the onion and bell pepper and continue to stir until vegetables are softened. Strain out any excess grease.
Stir in the chili powder, cumin, salt,oregano, and garlic powder, cooking for an additional 30 seconds.
Add chicken broth, Dr Pepper, diced tomatoes, tomato paste, and worcestershire sauce. Mix well and simmer for 20-30 minutes, or until chili has the desired thickness. Then, add kidney beans.
Serve with sour cream, red onion, and cilantro.
