Start a marinara sauce right with Rega San Marzano Peeled Tomatoes D.O.P.! Whole peeled tomatoes grown in Campania are steeped in tomato juice and basil. Bearing the DOP signature (Protected Designation of Origin) means that these San Marzano tomatoes are certified by European law to have been made in the original region of production. Enjoy the tomatoes as part of a red sauce over pasta, served in a salad, or roasted with peppers and onions.
