Preheat the Traeger grill to 225°F.

In a large pot, add a bit of oil and sauté the diced onion and bell pepper until soft.

Stir in the minced garlic and cook for an additional minute.

Add the ground beef to the pot, breaking it apart as it cooks until browned.

Mix in the chili powder, cumin, smoked paprika, salt, and black pepper.

Stir in the kidney beans and diced tomatoes, followed by the beef broth.

Pour the chili mixture into a large cast-iron pan and place it on the Traeger grill.

Let the chili cook for about 2 hours, stirring occasionally.
