2In a large pot or Dutch oven, cook the ground beef over medium heat until browned. Drain any excess fat.
Add the chopped onion and minced garlic to the pot. Cook until the onion is translucent, about 5 minutes.
Stir in the chili powder, cumin, and paprika. Cook for another 1-2 minutes to toast the spices.
Add the kidney beans, black beans, and diced tomatoes (with their juices) to the pot. Stir to combine.
Season with salt and pepper to taste.
Bring the mixture to a boil, then reduce the heat to low and let it simmer for at least 30 minutes, stirring occasionally.
Serve hot, and enjoy your Campfire Chili!
