Bring a large pot of salted water to a boil. Add the beans and return to a boil, then cook at a high simmer for 7 to 10 minutes until done to taste. Drain and pat dry.
Heat the oil over medium-high heat in a large skillet. Add the pancetta and saute 2 minutes, then add the beans and saute another 2 minutes. Lower the heat, stir in the paprika and the vinegar and cook 1 more minute before serving.
