ok...
Adding pulled pork and onion to a grilled cheese sandwich does not make it a pulled pork sandwich. A pulled Pork Sandwich is lot s of pork piled on a crusty bun with cheese onion and whatever else you like.
With a grilled cheese you butter the outside of the Sourdough bread, place your sharp cheddar, onion and a small helping of the pork together for a great sandwich entirely different than your standard grilled cheese.
Perhaps you know it alls should give it a try and you'll see how great they are instead of arguing semantics in a FUCKING FOOD THREAD.
