Flaky, all-butter golden pastry filled with a delicately spiced sweet filling, baked until crisp and aromatic.
Sauté the onion until soft, add the spinach until wilted, then cool and squeeze out all liquid.
Mix the spinach with the feta and dill.
Brush phyllo sheets with melted butter, spread the filling along one edge, and roll into a tight log.
Brush the top with beaten egg yolk and scatter with sesame seeds.
Bake at 190C for 30 to 35 minutes until deep golden.
Rest 5 minutes, slice, and serve warm.
