Split the rolls lengthwise without cutting all the way through, so they open like a book.
Spread 1 tbsp of mayonnaise on one cut side of each roll and 1 tsp of mustard on the other.
Lay 2 slices of provolone along each roll, then fold in 60 g of turkey and 40 g of ham.
Add the tomato slices and season them with a pinch of salt, pepper and oregano.
Top with the red onion, green pepper and shredded lettuce.
Close the rolls, press them gently and cut each in half at an angle.
Serve right away, or wrap tightly in paper and keep chilled for up to 4 hours.
