Heat oven to 200 C and line a baking sheet with parchment.
Lay one phyllo sheet on the board and brush with olive oil. Place a second sheet on top and brush again.
Spoon two tablespoons of filling along one short edge. Fold the sides over the filling then roll into a tight log.
Brush the seam with beaten egg to seal. Set on the sheet seam side down. Repeat to use all filling.
