Mix first seven ingredients and let stand at room temperature overnight.
Have all meats/cheeses sliced very,very thinly. The following day, slice a loaf of GOOD French bread horizontally. Scoop out some of the center of the loaf and drizzle wth olive oil, from the olive salad you made the night before, on both sides of the bread. On the bottom half, spread some of the olive salad. Then, layer the salami, Provolone, prosciutto, and Muenster, alternating until all are gone. Put more of the olive salad in the top of the loaf, and wrap the assembled sandwich in tinfoil (seam side UP) and bake @ 350 for 15-20 minutes.
This makes a LOT of relish, so if you like, it's easily halved.
