Giant Muffaletta Italian Sandwich

In a medium bowl, combine the green olives, black olives, giardiniera, red onion, capers, olive oil, red wine vinegar, oregano, garlic powder, and crushed red pepper flakes.
Stir everything together, then cover and refrigerate for at least 1 hour to allow the flavors to meld together.
Assemble the Muffaletta Sandwich:

Slice the muffaletta bread horizontally, making a top and bottom.
Spread a generous layer of the olive salad on the bottom half of the bread.
Layer the salami, ham, mortadella, provolone, mozzarella, pepperoni, and any additional roasted red peppers in a neat stack.
Add another layer of the olive salad on top of the meats and cheese.
Close and Press the Sandwich:

Place the top half of the bread over the sandwich and press down gently.
For added flavor and texture, you can wrap the sandwich tightly in plastic wrap and refrigerate it for a few hours or overnight. This helps the sandwich hold its shape and enhances the flavor.
Serve & Enjoy:

Slice the sandwich into wedges or large slices and serve! It’s best enjoyed with some chips, pickles, or a light salad.
