Cut phyllo sheets lengthwise into 2-in. strips; cut each strip in half widthwise. Using five strips at a time, brush each strip with butter and stack on top of one another. (Keep remaining phyllo covered with waxed paper to avoid drying out.) Place 1 teaspoon cranberry sauce and one to two cheese cubes at the end of each stack. Fold into a triangle as you would fold a flag.
Place in an ungreased 15x10x1-in. baking pan; brush with butter. Bake at 400° for 10 minutes or until golden brown. Let stand for 5 minutes before serving.
