Preheat the oven to 350°F. Grease a 9 x 13 inch-pan.
In a large pot, bring at least 4 quarts of water to a boil over high heat, add salt, and cook the noodles until done, but still firm to the bite. The time will depend on the noodles; see package directions.
While pasta is cooking, combine all other ingredients except cinnamon sugar in a large bowl.
Drain the cooked noodles and add to this mixture. Mix well. Pour into prepared pan and sprinkle with cinnamon sugar.
Bake in preheated 350°F oven for 45 minutes.
