This Muffaletta sandwich is the ultimate summertime crowd-pleaser. With layers of savoury deli meats, melty cheese, and a punchy, zesty olive salad, this hearty sandwich is made for slicing into wedges and passing around on a sunny afternoon.
Begin by making the olive salad. In a medium bowl, combine the chopped giardiniera, green olives, kalamata olives, roasted red peppers, and pepperoncinis. Drizzle with olive oil and red wine vinegar, then sprinkle with parsley and oregano. Toss well to combine and set aside.
Slice the sourdough loaf horizontally into two halves. Scoop out some of the soft bread from the centre of each half to make room for the filling. This will help keep the sandwich neat and easy to slice later.
Spoon half of the olive salad onto the bottom half of the bread, spreading it evenly. Layer on the capicollo, mortadella, and hot salami. Follow with the provolone and mozzarella slices. Top with the remaining olive salad.
Place the top half of the bread on the sandwich and press down gently to compact the layers. Wrap the entire sandwich tightly in parchment paper. Place a heavy weight on it (such as a frying pan with a few cans of tomatoes) and place the the fridge to press the sandwich. Refrigerate for at least 1 hour (or up to overnight).
When ready to serve, unwrap and slice into wedges. Enjoy!
Notes
If desired, toast the whole sandwich in the oven at 350 degrees F for 20 minutes before slicing and serving warm.
