Bring a pot of salted water to a rapid boil and cook the Bucatini al dente, about 5 – 6 minutes. Drain pasta and set aside, reserving ½ cup of the pasta water.
In another pot or large skillet heat the Arrabbiata Sauce. Add the cleaned mussels and the pasta water and cover. Cook on medium heat until the calms open, about 3 – 5 minutes.
Add the cooked pasta to the sauce and mussels and continue to simmer for about one minute.
Divide the pasta evenly among your plates, making sure to divide the mussels evenly as well. Garnish with fresh oregano and parmesan, and don’t forget an extra bowl for those mussel shells!
