Violet, I think the recommended serving size of spaghetti is 2 oz dry - that hydrates to about 1 cup cooked. So times 2 your thinking maybe?

I think a cup (8 oz wet) is a fair serving size, especially if you mix other stuff in. However, myself would eat 3 times that and have other stuff to boot. Some people can tolerate delicious pasta - I let them enjoy it. If your husband likes pasta, and can tolerate it, let him enjoy a full serving!
