Cinnamon Sautéed Apples and Pears

In a large skillet, melt the butter. Add the apple and pear slices and cook over moderate heat, stirring occasionally, until lightly browned in spots, about 5 minutes. Stir in the sugar and cinnamon, reduce the heat to low and cook, stirring occasionally, until softened and lightly caramelized, about 10 minutes longer.
