Mix together the flour, sugar and ginger in a bowl, add the sunflower spread and rub in with your fingertip to give coarse breadcrumbs. Stir the oats, Walnuts and raisins. Mix in 2 tbsp yogurt and set aside.
Heat the oil in a large frying pan and fry the pears, cut side down for 3-4 minutes until golden and caramelised, transfer to a medium roasting tin, cut side up so that they fit in snuggly. Press on the Walnut crumble mixture. Add 3 tbsp boiling water to the tin and bake for 15-20 minutes, or until golden and the pears are tender.
Serve with extra yogurt and Walnuts sprinkled over.
Cooks tip: Try with dessert apples instead of pears or swap the ginger for cinnamon.
