Fill the roasted peach halves with lightly sweetened ricotta cheese and a sprinkle of chopped toasted hazelnuts for an easy and elegant summer dessert.
Preheat oven to 425 degrees F. Cut peaches in half and remove pits. Toss the peach halves with lemon juice in a large bowl; add sugar and toss once again. Arrange halves cut-side up in a baking dish. Roast until the peaches are tender, 20 to 25 minutes. If the juices in the pan begin to burn, add a little water and cover the pan loosely with foil.
