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 20x30cm baking pan. Place pineapple slices decoratively over the top. Place a cherry in the center of each ring.
Bake at 180 degrees C for 50 minutes, or until golden.
