Pour jar of Pulled Pork Simmering Sauce over pork. Cover pot and bake for 2 1/2-3 hours until the pork can easily be pulled apart with a fork. Spoon the sauce over the roast several times during baking.
When done, remove roast from pot. Pull pork apart removing any fat. Add pulled pork back to the pot with sauce and stir.
Serve warm on a sandwich bun topped with coleslaw.
Pressure Cooker Instructions:
Cut pork shoulder into 2-4 smaller chunks to allow it all to fit into the pressure cooker. Set pressure cooker to sauté. Season the pork with salt and pepper. Add oil to the pressure cooker and brown the meat on all sides.
Pour the jar of Pulled Pork Simmering Sauce over the pork. Seal pressure cooker, close the valve and set to high pressure for 60 minutes.
When the timer beeps, allow the pressure cooker to naturally release pressure for 10 minutes. At that time you can quick release the remaining pressure and carefully open the pot.
Remove the pork from the pot and pull apart using 2 forks, removing any fat. Add the pulled pork back into the pot with the sauce and stir.
Serve warm on a sandwich bun topped with coleslaw.
