For the vinaigrette:
Combine all the ingredients in a glass jar and shake until they are well mixed. Taste and adjust salt and pepper.
Prepare the sandwich:
Cut the loaf of bread. Season the inside with the vinaigrette and lay the peppers cut into strips, cold cuts and sausages, a nice slice of Stracchino di Bufala Formaggi Tomasoni and finally the seasoned rocket.
Cover with the other half of the slipper. Place for a few minutes in the hot plate and serve.
