A simple roll stuffed with thick-cut Bologna mortadella is Italy's most iconic sandwich. This high protein mediterranean classic is a family favorite that proves simplicity wins.
Slice the Italian bread rolls in half lengthwise with a serrated knife. Drizzle the cut sides with half the olive oil.
Layer 3 oz of thick-sliced mortadella onto the bottom half of each roll, folding the slices for extra height and texture.
Top the mortadella with 1 oz provolone cheese per sandwich. Add a pinch of sea salt and freshly ground black pepper.
Brush the top roll halves lightly with the remaining olive oil and toast the open sandwiches under a broiler for 2–3 minutes until bread edges are golden and the cheese just begins to melt.
Close each sandwich, press gently, and rest for 1–2 minutes to let flavors meld slightly. Slice and serve immediately for best texture.
