Steam the spinach until it wilts.

Run the spinach under cold water to stop the cooking process.

Squeeze the spinach and drain.

Mix the spinach, the feta, the dill, the pepper and the nutmeg in a large bowl.

Preheat the oven to 180 degrees celsius.

Take one phyllo sheet and cut three lines from it.

Lightly cover the surface with olive-oil, put a heaping teaspoon of filling near the corner of one of the lines, then fold the corner of phyllo over to enclose the filling and form a triangle.

Fold away from you towards the top edge.

Continue folding maintaining a triangle shape. Put the triangle, seam side down on a baking sheet covered with baking-paper.

Bake the triangles in the middle of the oven until golden brown, 20 to 25 min.
