Why don't you test it out? Just add hot water to regular ol' pasta and see what happens.

There is a change in the pasta that happens during cooking - when you boil pasta and then dehydrate it, then add hot water to it (no boiling the pasta in the pot) on the trail, you have a just-add-water meal. No pot to scrub. Adding water to dried raw pasta (what you get from the store) will result in moist dry pasta, or a sticky glop, depending on how hot the water is and how long you soak it.

BTW, I don't freeze it. Dehydrated cooked pasta will keep a good long time if stored in a sealed container.
