The "Zep" was invented in the 1950's by my Good Friend "Pepper Joe" Arditi in Norristown, Pa. Slice a Keyser Roll, add 2 slices of Cooked Salami, 2 slices of Provolone Cheese. Layer with thick sliced Tomatoes and Onions. Coat one side of the Roll with Olive Oil and add salt, and Oregano to your taste. ENJOY!!
