This sandwich is an interpretation of the famous quattro stagioni pizza:
Prepare the sandwich, and slightly warm it up in a hot oven.
We imagined keeping the condiments separate, so as to form 4 bites: one with ham, one with artichokes, one with olives and one with mushrooms keeping tomato and mozzarella as a substrate.
It's a great idea when you want to share something with your friends and family.
