Transfer the cooked beef mixture to your trusty slow cooker. Add the diced tomatoes with their juices, hominy, black beans, pinto beans, corn, tomato sauce, taco seasoning, dry ranch dressing mix, and cumin to the slow cooker. Pour in the beef broth or water. Stir everything together until well combined. If you like a less thick chili, you can add a bit more broth or water.
