In a medium sized skillet cook the ground beef, onion, and garlic until beef is no longer pink. Drain the grease and add to slow cooker.
Add green bell pepper, jalapeño, corn, black beans, tomatoes, chili powder, salt, pepper, red pepper flakes, and chicken broth and stir to combine. Cover and cook on low for 4 hours.
Serve warm with desired toppings.
The fire roasted salsa style tomatoes that I use are the Great Value brand from Walmart. I've also seen the salsa style at Smith's (Kroger brand).
