Muffuletta-Style Deli Stack on a Seeded Bun

The New Orleans muffuletta is famous for its olive salad, a chunky relish of olives, pickled vegetables and oil that seasons every layer of meat. Here that idea moves onto a single sturdy seeded bun for an individual stack. Make the olive salad at least an hour ahead, overnight if possible, so the flavors blend. Fold the meats into loose ribbons rather than flat sheets for height and tenderness, and give the finished sandwich ten minutes wrapped and pressed so the oil soaks in.
