Ok so I measure out 2 cups of cooked rotini. The box says serving size is 2oz, I'm assuming they use uncooked noodles for that measurement right? How would I know how much Ive used lol? So 2cups = 16oz right, buuuut... noodles expand when they cook from water absorbtion. Sooo.. how many oz, for nutrition measurement purposes, is 2 cups of cooked wheat rotini?
