Preheat the oven to 170C Fan. Lightly grease a baking tray using the cooking oil spray.

Place the apples, raisins, cinnamon and stevia into a bowl and mix by hand.

Lay out a sheet of the filo pastry and lightly spray it with the cooking oil. Lay another sheet on top and repeat this process until you have used all of the 6 filo pastry sheets.

Arrange the apple mixture lengthways evenly along the centre of the pastry to within 2-3cm of each edge. Fold the two shorter edges over the filling and then roll the sheets up to form a log shape.

Lightly spray the strudel with the cooking oil spray. Then carefully transfer it to the greased baking tray.

Bake for 35-40 minutes, until the pastry is crisp and golden brown.

Leave the strudel to cool down slightly. Dust with a light sprinkle of stevia and serve with a little fat free, sugar free vanilla ice cream or a dollop of fat free Greek yogurt.
