Open the can of Ro*Tel and pour it into the blender. Blend on high until perfectly smooth. Pour the tomatoes into a heavy-bottomed saucepan (*See Notes). Add the Velveeta cubes and cook over low heat, stirring frequently, until the cheese is fully melted. Stir in the pulled pork and continue stirring and heating until the pork is heated all the way through. Transfer to a bowl and serve immediately.
