Well this is an opportunity to learn and use up your present brand. Take one day and live on the ration alone, monitoring your water intake and problems repacking the unused portion.
You can make a bulliun cube broth, brew some instant coffee and pour that small bottle of tobassco sauce on rabbit roadkill.
Now once again: who would rather pack 5 knives in their BOB or
some chocolate bars, a few cans of Dinty Moore stew and a '58 Chateau laFitte Rothschild?
I did that once for 3 days. It wasn't bad - food wise I actually felt full most of the time. Did get a bit thirsty after each one. But, boring it certainly was. That being said, I did replace them with the same product (forget the name, it't the yellow package with black stripes). Didn't have any true "flavor" like lemon, but it was kind of dry-cookie texture. Very crumbly.
