Heat the oven to 200C/400F/gas mark 6. Cook the macaroni as per the packet’s instructions.
Place all the ingredients in a large bowl, except for 50g of the grana padano. Gently mix until all the ingredients are distributed evenly, then use a spatula to empty the ingredients into a baking tray and level off.
Finish by topping with the remaining grana padano. Bake in the oven for 30-35 minutes until golden brown and serve with seasonal greens.
