Preheat the oven to 190c fan
Place the butter in the base of a roughly 25cm wide pan that can be used on the hob and in the oven. Drizzle over the honey. Arrange the squash rings neatly in an overlapping circle and completely cover the base. Sprinkle over the rosemary, salt & pepper
Cut the pastry into a round the same size as the pan. Cover the squash with the pastry and tuck in any excess. Stab the pastry all over with a sharp knife. Place on a medium heat for five minutes, then transfer to the oven for 30 mins. Set aside for 5 minutes before very carefully turning out onto a plate or chopping board
Top with the mozzarella, hazelnuts, chilli flakes and basil leaves
