Place the stracchino cheese in a bowl and mash it with a fork until it becomes a bit creamy.

Roughly chop the walnuts in a food processor and mix them well into the stracchino cheese.

Slice the bread (I used sandwich bread, but rustic bread works great too) and toast the slices under the broiler for a few minutes.

Spread a teaspoon of the stracchino and walnut mixture on each slice, add a piece of salmon, then broil for another couple of minutes. Serve warm.
