I like smoking Pork Spareribs because it's meaty, simple and makes great leftovers for the week.  Costco usually sells the ribs in a 3 pack rack and use a dry rub with lots of spices or simple salt and pepper, no sauce needed.

1. Set pellet smoker temperature to 350 F
2. Season ribs with any dry rub
3. For an easy clean up, I place ribs on a sheet pan lined with butcher paper.  
4. Ribs are done in about 2 hours or when rib bone is visible, no meat thermometer needed.
5. Rest the ribs about 30 minutes to 2 hours in the oven for a tender moist bite.
