The way the Bar-B Q Shop,Interstate,and Neely's do it in Memphis is pretty basic.
Brown a med onion and a clove of mashed garlic in a couple Tbsp of butter.
Mix with a pound of cooked spaghetti.
Add a couple cups warmed pulled pork and about a cup warm memphis style sauce.
Add a little more sauce if you think it needs it.
Plenty of freshly ground pepper is essential.
Serve immediately.
Some chopped yellow onion on top,if requested.
