Ok, Kraft EasyMac comes with the most vile chemical-laced sauce known to humankind. BUT the dried pasta itself, which is separate, appears to have been pre-cooked. So it can be reconstituted with a 10min soak in hot water.
This makes it ideal for easily plumping up a pasta-based freeze-dried meal, as you can just throw the extra pasta in and let it all absorb as usual.
I find most freeze-drieds to be over-sauced anyway, so it works for me. But if you value your body, whatever you do, DON'T EAT THE SAUCE.
