Start by setting up your grill to cook indirectly. Fill a chimney starter with coals and light. Once they begin to ash over pour them into charcoal baskets or onto your charcoal grate.
Cover the grill and let the temp come to 275 degrees.
Season the sausage with the bbq rub and place on the grill away from the coals and cook until the internal temp is 165. Sauce the fatty and remove it from the grill. Slice the smoked fatty into medallions or crumble to use in recipes.
Notes
There are a million ways to eat smoked fatties. Start by eating it with slaw and beans for a nice sweet and savory contrast.
