Heat oven to 375F and stir the pumpkin, feta, egg, parsley, and salt together.

Brush a phyllo sheet with butter, layer a second on top, and cut into long strips.

Place a spoon of filling at one end and fold flag-style into triangles.

Brush the tops with butter and arrange on a baking sheet.

Bake 18 to 20 minutes until golden and crisp.

Cool slightly before serving so the filling sets.
