Both packed by Sopakco

But one is a lot fatter. HMMmmmmm?

Here's what's in the skinny one - just what we'd expect. (FRH, Acc pack and warming sleeve not shown.)

And here's what's in the fat one. Extra goodies at left.
So whoever packed these threw in both a side dish and some wheat snack bread. In essence, it's a whole MRE instead of the reduced-content version. Odd, but a most pleasant surprise.
Supposedly, there is no fixed menu for TOTMs, unlike MREs. In other words, beyond the basics of an entree, drink, snack/dessert, FRH and Acc pack, there are no set rules for what is included. They very often do not contain a bread/cracker pack or a spread, for example. And never a side dish. Except for this one - which has both!
