its not what you are looking for but this is a commercially available powdered product, but a pretty good soup mix. Just add 4 cups of water. Big portion and tasty:
Idahoan Loaded Steakhouse Soup Red and Russett (2 Pack)
I havent tried this one:
Bear Creek Soup Mix, Cheddar Potato, 12.1 Ounce (Pack of 6)
You can try to get a full FSR #7 or #9 off of ebay too. They are easy to get for around $25
i tried the MRE version and you can try to hunt down a 2009 to 2013 rib menu (#2 then changed to #16 in 2011) the soup item was in there. I gave just the soup a try here, as part of another meal:

Idahoan products are amazing, just add water and you get some creamy/smooth mashed potatoes, those are your best bet for now
