Here's some ideas from another site: (I am just cutting and pasting the posts)
Steal away... I "borrowed" the turkey SPAM can idea from somewhere on the Internet... we all share ideas
Here's an idea from a friend ... send an inexpensive micocassette taperecorder. Buy one for yourself, everyday tape a few minutes of chit-chat, at end of week send tape for him to play. The lovely lady who suggested this is a wealth of creative ideas. Sending pictures of you during the week would complete the "memories" package!
Some of my ideas for this year...
teeny 8" or smaller tree with Xmas lights,
an Advent calendar (non-religious so as to not violate the mailing regs),
hand made cards from my students to a larger group,
Christmas cookies,
fudge,
movie DVDs of Christmas movies (not my idea, the awesome friend again),
stamps & unwritten cards for them to send back to whomever,
computer generated stationary with their name nicely printed on good quality paper (with matching stamped envelopes) ... an inexpensive but highly personal gift.
a collage of holiday pictures from years past (dont send oroginals, make copies in collage form at WalMart), pocket calendar for next year with family picture on it (again can make at WalMart)
local news clippings..holiday tree lighting, etc...
tang, koolaid, powerade powder
toys.. small, silly putty, nerf football, etc
a handwritten story or poem..done by you
my criteria... small, disposable if need be, meaningful

Ok... here goes... Thanksgiving dinner for soldiers (or Christmas!)
Pumpkin bread (I made it, triple wrapped it in Press & Seal)
SPAM has a canned turkey breast Its the white meat only, but.it's TURKEY!
Canned Turkey Gravy (Metal can not glass)
Canned cranberry sauce (Metal can)
package of homemade biscuits to have with the gravy
Can of veggies (I sent corn)
1 package of microwaveable (or they can be made on a stove with just water & powdered milk) mashed potatos (they come buttered & spiced)
powdered milk for potatos & to have with pumpkin bread
All they'd need is a heat source OR knowing my son, if he can't find one depending on where he is, he'll eat the stuff cold.
Throw in a few pieces of candy, the sports page or football magazine & it's ALMOST like home because.. it's made & sent with love
Viola.. thanksgiving dinner from home.
