Heat oven to 220C/200C fan/gas 7.
Heat half the oil in a non-stick frying
pan. Tip in the onions and cook until
soft and golden, about 8-10 mins.
Meanwhile, boil the potato cubes for
5 mins, until just tender, then drain. Tip
into the softened onions and fry for
2 mins more. Stir in the curry paste and
cook for 2 mins. Pop in the peas, plus
1 tbsp water. Cook for 1 min, give
everything a good mix and season. Tip
into a bowl to allow to cool slightly.
Brush half the filo half-sheets with
some of the remaining oil, then lay the
remaining sheets on top so you have
4 x double layers. Spoon a ¼ of the
potato mix along one edge of each,
leaving a bit of space at each end. Fold
in the ends then roll up to seal. Place
seam-side down on a baking sheet,
brush with the remaining oil and bake
for 20 mins, or until crisp. Serve warm
with a dollop of mango chutney and a
tomato & onion salad, if you like.
