Most common ways of serving them around here are to put into a saucepan and cover with BBQ sauce and simmer 5-10 minutes until hot, or wrap in a biscuit dough and bake until done - usually using canned biscuits of one type or another which can be buttermilk, crescent rolls, puff pastry, etc. They can also be treated as a summer sausage and eaten cold with a piece of cheddar cheese and crackers.
