Heat the oven to 130C (fan) and line a baking tray with greaseproof paper. Add the oil and honey together in a small saucepan and heat gently until well combined. Take off the heat and allow to cool slightly.
Mix together all the dry ingredients (apart from the fruit), in a large bowl. Stir the honey and oil mixture into the bowl until well distributed. Beat the egg white in a separate bowl until frothy, then mix in.
Spread the mixture out on the baking sheet and bake for about 30-35 minutes until golden. Stir regularly so it cooks evenly.
Leave to cool and crisp up on the tray, then stir in the fruit. Store in an airtight container.
