Slice loaf of bread or buns in half horizontally so you have a top and bottom. Lay them open in front of you.
Spread olive bruschetta equally over tops and bottoms of bread.
Then layer 1/2 of cheese, meat and remaining half of cheese.
Place top half of bread on top, wrap carefully with parchment or plastic wrap. Place on a plate, put another plate on top to weight it down, then place in fridge until ready to enjoy.
If made individually, these are ready to go. If it is a large round, cut this into about 6 wedges.
Optionally, you can grill these in a panini press or weight down in a regular frying pan. (Not traditional but a tasty alternative.)
