Suggested Garnishes: sour cream or plain Greek yogurt, shredded cheese, queso cheese dip (I got mine from Trader Joe's), crushed corn chips, fresh chopped chives.
Add all ingredients (except the optional garnishes) to an 8-quart slow cooker and mix well to combine. Place the lid on the slow cooker and cook on HIGH for 6-7 hours or on LOW for at least 8 hours. Season to taste.
When ready to serve, garnish as desired. Store leftovers in a sealed container in the refrigerator for up to 4-5 days.
