Salmon Sandwich with Wasabi Mayonnaise

This was a really lovely sandwich, with a hint of horseradish from the wasabi. I served it on homemade wholemeal bread.
















Salmon Sandwich with Wasabi Mayonnaise (from Rajib's Collection)
(Serves 4)

6 tbsp low fat mayonnaise
2 tbsp rice vinegar
1 tbsp grated ginger
11/2 tsp wasabi powder
1 tsp mirin
2 tins salmon, drained and flaked
2 spring onions, chopped
1 tbsp sesame seeds, toasted
8 slices wholemeal bread
1⁄3 cucumber, thinly sliced
50g watercress

Stir together half the mayonnaise, the rice vinegar, ginger, wasabi powder and mirin in a bowl. Add the salmon, spring onions and sesame seeds and mix well to combine.

Spread the rest of the mayonnaise over one side of each slice of bread. Divide the salmon mixture evenly among four of the slices. Top with cucumber slices and watercress. Put the remaining bread slices on top. Serve.
