Preheat the oven at 180C/350F and grease an approximately 10-inch skillet or any ovenproof dish.
Peel and core the apples, wash and chop into small cubes.
Add the sugar and the cinnamon and set aside.
To the chopped apples add the cranberries, the beaten eggs, the rolled oats, the Goji berries, salt, yoghurt and the sunflower seeds.
Mix all pretty energetic until it gets all very well mixed.
Place the mixture into the prepared tray and bake for around 40 minutes at 180C/350F.
Sprinkle with the chopped walnuts or mix those into the actual mixture before baking and serve either hot with a scoop of ice cream scoop or can ve served cold with a dollop of creme fraiche.
Notes
Serve cold or warm with a dollop of ice cream, clotted cream, or a good natural Greek-style yogurt. Of course, you can substitute the apples with a fruit that you love and this can be bananas, apricots, pears, cherries, or nectarines.
