Add your diced onion and bell peppers to the same pan. And sauté in the bacon fat for about 10 minutes.
Then add the ground beef and season with salt and pepper. Break up the meat with a spatula and incorporating the peppers and onions. Cook until the meat is no longer pink. Then transfer the mixture to your slow cooker.
Now stir in the crushed tomatoes, garlic, oregano, smoked paprika, coriander, cumin, chili powder, salt, and pepper. Stir it all up. Set your slow cooker to low for 6-7 hours.
