Rinse beans thoroughly. Sort and inspect for any unwanted debris and discard. Set seasoning packet aside.
Pour beans into the bottom of a 6 quart slow cooker.
Add onion, carrot, celery, garlic salt, red pepper flakes, chicken stock, butter and bay leaves. Mix well.
Cook on high for 4 hours then add the seasoning packet, lemon pepper, ham and tomatoes. Stir to combine.
Continue to cook for an additional 1-2 hours or until the beans are tender.
Serve with a slice of corn bread or serve over rice garnished with green onion..
Notes
May use ham bone for extra seasoning, if desired. Add at the beginning with the beans. Please keep in mind that every time the lid is opened, your cooking time will be longer.
