Preheat oven to 180°C and grease a baking dish.
Cut up the bread. I sliced it, but I will probably dice it next time. Arrange the bread slices in the greased dish.
Cut up the nectarines, prop a few pieces between the bread slices and scatter the rest over the top.
Mix eggs, milk, cinnamon and sugar/sweetener.
Pour the milk-egg-mixture over the bread and nectarines and bake for about 45 minutes.
