Drain off the Fruit Mostarda but keep a spoonful of syrup back to be used in the dressing and then cut the fruit up into cubes.
Prepare six salad plates with the lettuce.
Warm the oil in the frying pan and add a clove of garlic and the cubed bread, fry them until the croutons are crispy and golden all over. Remove the garlic and remove the excess oil from the croutons using kitchen paper.
Prepare the dressing. Put all the dressing ingredients, as well as the remaining spoonful of Cremona Mostarda syrup into a glass jar with a lid. Shake the jar until the ingredients are well blended.
Put the croutons, walnuts, cheese and fruit mostarda on top of the lettuce leaves.
Dress the salad with the previously prepared dressing and serve immediately.
