Begin by preheating your oven to 350°F (175°C) if you plan to warm your focaccia later. Carefully slice a rectangular piece of your focaccia bread in half lengthwise using a serrated knife.

Take the bottom half of the focaccia and spread a thin layer of pesto sauce evenly over the surface.

Gently tear the burrata cheese into small pieces and place them on top of the pesto layer. Sprinkle a pinch of salt and black pepper over the burrata.

Layer the thinly sliced prosciutto evenly over the burrata, followed by a layer of salami. Use fingers to distribute uniformly.

Scatter a handful of fresh arugula over the meats, drizzling with olive oil and sprinkling with more salt and pepper.

Carefully position the top half of the focaccia over the assembled layers and press down gently to secure the sandwich.

Slice the sandwich into portions for easy serving. Serve immediately with BBQ chips for added crunch.
