In a bowl, combine sugar, eggs, and oil and mix well. Stir in flour and cinnamon (batter will be thick). Stir in apples and nuts. Spread into a greased 13in x 9in x 2in baking pan. Sprinkle with chocolate chips. Bake at 350 degrees for 35-40 minutes or until golden and a toothpick inserted near the center comes out clean. Cool before cutting.
