Preheat oven to 200*C.
Throw the oatbran and apple into your food processor and mix it until the apple is virtually mush.
Add the egg whites and the protein powder and mix some more and add water to suit. I used about 125ml to make it easier to spoon into muffin tins.
Throw in the blueberries at the last minute and pulse quickly, you don't want them demolished.
Spoon the mixture into lightly greased muffin tins. This made 12 muffins.
Bake for about 30 minutes until they are slightly browned on top.
