Preheat the oven to 200 degrees C. Put the cucumber sticks in a bowl and sprinkle with a little salt. Mix well, then leave for about 10 minutes. (This draws out some of the moisture so that the filling in the wraps will remain crisp.)
Wrap the tortillas in foil and warm in the oven for 5 minutes, or according to the packet instructions. Put the cream cheese, yogurt, chives and dill into a small bowl and mix together. Stir in the flaked trout and season to taste.
Separate the tortillas and spread out on two large boards (alternatively, you can prepare four tortillas at a time). Spread each tortilla with one-eighth of the trout mixture.
Rinse the cucumber in a sieve, tip onto paper towel and pat dry. Divide among the tortillas, arranging them lengthways so the tortillas will be easier to roll up. Scatter over the bean sprouts and salad leaves.
Roll up the tortillas tightly to enclose the filling. Cut each rolled tortilla in half on the diagonal and serve four pieces per person.
*Smoked salmon or shredded smoked chicken breast would make equally delicious alternatives to the smoked trout. *Wraps are also delicious filled with taramasalata. Spread the warm tortillas with 200g light taramasalata. Grind over a little black pepper, then scatter with 1/2 finely diced telegraph cucumber and 1/2 deseeded and finely sliced yellow capsicum. Sprinkle with the leaves of 2 shredded baby cos lettuces before rolling up.
