Prepare Peperonata and keep warm.
Fill a very large saucepan two-thirds full with salted water.
Bring water to a boil.
Bring water back to a boil and cook rigatoni uncovered until tender but firm to the bite, 8 to 10 minutes.
Drain rigatoni and place in a warm deep dish or bowl.
Pour Peperonata over rigatoni.
Season with pepper.
