In a 10-inch skillet, add the sausage, ground beef, celery, onion, and garlic. Cook over medium heat (~8-10 minutes), stirring occasionally until the meat is no longer pink; drain.
In a slow cooker, combine the meat mix and remaining ingredients.
Cover and cook on low heat setting for 5-6 hours
Turn off the slow-cooker, let its contents cool, and transfer to the refrigerator (the flavors really meld over-night)
The next day cook in the slow-cooker, on the low heat setting, another 2 - 3 hours
Serve and enjoy!
