Pumpkin feta filo triangles

Method

1. Preheat the oven to 200°C (400°F) and line a baking sheet with baking parchment.
2. In a medium bowl, mix together the pumpkin, feta, egg, salt, chili flakes, and pepper.
3. Lay out a sheet of filo pastry on a clean work surface and cut into three-inch strips lengthwise. Using a large soup spoon, place a dollop of the pumpkin mixture at the top right-hand corner of the filo strip. Take the top right-hand corner and fold over the pumpkin mixture to the left. The strip should now have the beginnings of a triangle, with the peak at the upper left-hand corner. Continue folding the strip in the shape of a triangle (as if you are folding a flag), brushing the filo pastry with olive oil before each fold. Once you've reached the end of the strip, place on the baking sheet and brush with egg white.
4. Continue until all the pumpkin mixture has been used, making about 15 triangles.
5. Bake for 30 mins, or until the filo is crispy and a dark golden brown. Serve immediately.
