Prepare the filling: in a small bowl mix all the ingredients until evenly combined.
To make the roll-ups lay each tortilla on a clean work surface. Spread a thin even layer of the filling over the top, and then place a piece of smoked salmon on top. Put a sprig of dill on the center of the salmon. Roll up the tortilla.
Working with two roll-ups at a time, pierce one pre-soaked skewer through one and then the other roll-up, 5cm from the ends. Repeat on the other side. Continue with the other three parts.
Brush the roll-ups lightly with oil. Place each set of roll-ups on your barbecue over direct medium heat, for just long enough to warm and score the tortilla, approx. 4 minutes, turning once halfway through the cooking time.

To serve, carefully remove the skewers. Slice into halves or thirds and arrange on a platter and garnish with dill and lemon wedges.
