The older meals you could get very creative with, especially with the dehydrated items, but you are challenged with many of the newer entrees since they are so flipping designer. I don't even know what all the current main menu items are anymore.
Old school strawberry shortcake...take the dehydrated strawberries, add the coffee creamer and sugar packets, crush the crackers and stir them in and enjoy...was better if you had extra creamers and sugar packets. Could do the same with the dehydrated peaches, but you got peach cobbler instead...
Bar, cookie, chocolate covered...cover it with the peanut butter...that was a version of Ranger Cookie. Also taking the cocoa powder, add some water to the packet, add coffee creamer and sugar packets...I used to save sugar for this, 5 or six packets I would dump in there for the "perceived" energy, wala, Ranger pudding...a variance was, again, add crushed crackers and you had Ranger Chocolate Cake
Warm the spaghetti main meal and cheese spread...dump the cheese in the spaghetti, crush the crackers and stir in the hot sauce (or not), sorta like spaghettios with crushed crackers .
Most times it wasn't as much about making it taste good or really being a creative ass, but simply camouflaging as much as you can to make it edible...hot sauce does that for damn near everything.
Mostly I was always just crushing crackers and mixing them into whatever the entrée was...you couldn't eat those damn things by themselves cause they suck every ounce of moisture from your mouth, your throat, your gut, you get the picture...used to have cracker challenge to see who could eat the most of those damn things without any water...we actually let a dumbass cherry choke a little on those one time. I also cooked a lot of raman in my canteen cup and added (you guessed it) crushed crackers and however much of the main meal I could fit in the cup, plus hot sauce...food of the gods.
