Breakfast pastry - > Could either be a poptart (limited life) or MRE cinnamon bun ($2.36) / Filled French Toast ($1.29)
Pocket Sandwich (x2) - > $2.89 / per
Cheese or Peanutbutter - > $.50 - $.99 (or less via Treesuit!

Cracker - > $.25 (as above)
ERGO? - > Gatorade or power drink package? Not quite the same...
First Strike Bar (x2) - > Some sort of power bar
Desesrt Bar - > Same as above, but smaller
CHO Applesauce - > No clue
Caffeine gum -> Several commercial possibilities
Nut Fruit Mix - > $.75
Beef Jerkey (x2) -> Exising MRE beef jerkey or commercial
If you decided on only 1 pocket sandwhich, then you would go this path:
Packet tuna / chicken
Tortillas - > $1.39
Packet Mayo
Hotsauce
Throw in an accessory pack of your choosing with spoon and ziplock bag. Vacuum pack it all together.
Now, I know some members have lots of MRE components laying around (Treesuit) who may be able to provide some of these. There are the MRE beef jerkey, drink mixes, etc...) Then fill in with the comercial products.
I don't have all costs figured in. This was just preliminary thoughts. A standard MRE is around $5. This would replace 3, so around $15. Not sure if you could independently build one under that cap. I'm sure a good # of members have a vaccum packer. It is a matter of getting just the right contents together.
