Grate the apple (minus the core and pips) using a cheese grater and place in a saucepan with the sugar and a dash of milk (approx 2 tbsp). On a medium heat bring to a simmer and stir for a couple of minutes until the apple softens and caramelizes. Using the bowl you are going to serve the porridge in pour in the apple and return the pan (no need to wash) to the hob. Add the oats, milk, cinnamon, sultanas and chia seeds to the pan and bring to a simmer. Add the apple and blueberries. Simmer on a low heat for 3-4 minutes stirring occasionally. Pour into a bowl and decorate with a sprinkle of cinnamon and your favorite fruits. I poured a little Oatly oat cream over the top. Enjoy!
TIP: When simmering the grated apple (I left the skin on) you want it to slightly caramelize. This will create a rich flavour that compliments the oats. Use gluten free oats to make this a gluten free recipe.
