Set a large deep skillet over medium-high heat, add the beef and season it with salt and a pinch of black pepper. Cook, using a wooden spoon to break the meat into small pieces as it browns, 4 to 5 minutes. Drain the liquid from the pan. Add the onion, bell pepper and garlic to the meat and cook until fragrant, 3 to 4 minute
Transfer the mixture to a slow cooker and add the cilantro, tomato, tomato sauce, brine, cumin, garlic powder, bay leaves and 1 1/2 cups water. Cover and cook on high for 3 to 4 hours or on low for 6 to 8 hours.
Serves 4 .. leave some for leftovers!
