COOKING INSTRUCTIONS Rub beef cheeks with salt, pepper and chili powder on both sides.
Heat a heavy-bottomed skillet over medium heat.
Add ghee to hot pan.
Once ghee is hot, add the beef cheeks and brown on both sides, about 3 minutes per side.
Set aside.
Add the onion to the pan and sauté until soft, about 5 minutes, then add garlic and sauté until fragrant, about 1 minute.
Add tomato paste and tomatoes and scrape the pan with a wooden spoon to get up any brown bits.
Place browned beef cheeks in the slow cooker.
Pour the tomato-onion mixture and beef broth over it.
Cook on low heat for 8 hours.
