I'm sure if you assembled the ingredients in a safe and proper manner, you could probably seal them into a 5 gallon bucket. Maybe?
That can be done but I've seen it more with whole foods like bulk beans , hard wheat and rice.
The trick is to pour in your goodies and place a little chunk of dry ice on top of it , put the lid on but not sealed to allow breathing , let the dry ice shrink up and then seal the lid , always use new buckets and lids too.
If I am wrong about this method someone feel free to chime in , please.
Does anyone know where to get this cheap or an equivalent alternative freeze dried food?
I did some searching and all prices I found were about the same on various foods.
Personally I just go with MRE's , you can find them reasonably priced on eBay and you cannot go wrong with them as far as flavor and quality and longevity.
In that little box there are 14 complete meals (entree , rice and apples in sauce)
Here is the Beef Stew entree , with some of Lousiana's finest
Even without sauce or pepper , itis very edible and tasty.
