You 'cooked' the pasta... The TS wants to simply rehydrate it... Meaning just add boiling water to a ziploc freezer bag, let it sit for a couple minutes and be done. You used fuel, time and dirtied a pot. (Not that dirty I know but it would be if you added sauce directly into the pot, which the ziploc method eliminates.)
I've heard of people making full on spaghetti, sauce and all, and dehydrating on fruit roll up trays so that it just needs hot water and its done... Haven't tried yet though.
