Halve pears, remove the kernels, dock the skeen.

Break the cookies, mix with butter and cinnamon, put on a foil, shaping round layer. Turn the foil edges, making high rims. Put over pears, then scatter berries and season with sugar. Cover with a sheet of foil and bake for 20 minutes on a grill until pears soften.

Cool prepared dessert, cut into portions and serve.
