1 Preheat oven to 200˚C (400˚F/ Gas 6). Using a sharp knife, cut the 4 sections of flesh from each halibut steak, discarding the skin and bones.
2 Trim and thinly slice fennel. Melt 15 g (½ oz) of the butter in a small saucepan. Add fennel and fry gently for 5 minutes, until softened. Remove from the heat and stir in lemon rind, parsley, salt and pepper.
3 Halve the pastry. On a lightly floured surface, roll out one half and cut out a 23 cm (9 in) round. Transfer to a dampened baking sheet. Arrange fish pieces, in a single layer, over pastry round to within 2.5 cm (1 in) of edge. Season with salt and pepper.
4 Spread fennel mixture to within 2.5 cm (1 in) of edges of fish. Dot the fennel with remaining butter.
5 Roll out remaining pastry and cut out a 24 cm (9½ in) round. Brush edges of pastry base with beaten egg then cover with larger circle. Press edges together firmly and flute with the back of a knife. Brush with beaten egg. Using tip of knife, make a decorate pattern from centre to edges. Bake for 30-35 minutes, until well risen and golden.
6 Meanwhile, cut peppers in half, discard cores and seeds and dice flesh. Quarter olives lengthways. Heat oil in a saucepan. Add peppers, olives, chilli powder, tomatoes and sugar and bring to the boil. Simmer gently for 6-8 minutes, until slightly thickened.
