3: Chop the herbs (you will need about 3 tablespoonsful) and put these into a bowl. I suggest a combination of parsley, chives, coriander and dill, but use what you have available.
4: Add 1 tablespoon Mustard, wholegrain if possible.
5: Add the salmon julienne...
6: ...the chopped hard-boiled eggs...
7: ...and mix thoroughly. This should not need any extra salt, but you can add pepper.
8: Lay a sheet of brik (or filo) on the work surface, then brush with olive oil.
9: Lay a second sheet on top...
10: ...and brush this with oil as before.
11: Place 2 tablespoonfuls of filling near the edge of the pastry.
12: Then roll up neatly. Use up all the filling like this.
13: Cut the rolls into sections.
14: Push toothpicks (cocktail sticks) through the rolls to stop them unrolling during cooking. Stand them upright on a baking sheet.
15: Bake for about 7 or 8 minutes, until the brik or filo sheets are crisp.
