Grill-Baked Apples in Foil with Cinnamon and Sugar is a delicious and easy dessert that can be made on the grill. The apples are filled with a sweet and aromatic mixture of cinnamon and sugar, then wrapped in foil and grilled until tender. The heat from the grill caramelizes the sugar, creating a gooey and flavorful filling. Serve these warm and comforting apples with a scoop of vanilla ice cream for a delightful treat.
