Prep. Add the barbecue sauce, pasta sauce, and pulled pork to a large pot, then stir to combine.
Cook. Simmer over medium low while you cook the spaghetti. (For an extra smoky kick, let it simmer in a metal pan in your smoker or barbecue pit at 225°F for 15 minutes.)
Boil. Bring 4 to 6 quarts of water to a boil in a large pot and prepare spaghetti according to the instructions on the package. Once cooked, drain the spaghetti and return it to the pot.
Add the sauce to the spaghetti and heat the mixture over medium-low, stirring frequently until the noodles, sauce and meat are combined and heated through, approximately 4-5 minutes.
Serve. Plate the BBQ spaghetti for your family members and dust each serving with Memphis-style dry rub.
