Boil noodles in boiling salted water just until softened; do not cook through. Rinse, and drain.
Beat the eggs with the melted butter. Mix in sugar, crushed pineapple with juice, vanilla, and cinnamon. Stir in the noodles. Spread into a greased 9 x 13 inch baking pan. Place pineapple rings decoratively over the top. Place a cherry in the center of each ring if desired
Bake at 350 degrees F (175 degrees C) for 50 minutes, or until golden.
