OK, then you do have some time and storage capabilties. I also know they have a good commissary out there. Here's what I do so that I don't have to put salads together every time I want to eat. Pick the veg you like, mix up enough to last 2-3 days. Mix it up. Just as an example, I'll use about 1/3 16 oz bag of frozen snow Peas , thaw them out, same out of sliced carrots, thawed (if fresh for either, steam them up abit), mix it up w/ 1 16 oz can Italian gr beans, 1 16 z can reg green beans, 1 8 oz can of either Lima or Garbanzo's, and 1 8 oz can of slicd green salad or black olives. Slice up some red onion, mix all togetherand throw an olive oil/lemon juice all over. Another favorite I like is similar, 1 med zuchinni, cut lengthwise, then sliced into half moons, 1 2 lb bag california veg (brocolli, cauliflower, carrot) thawed and sliced onions. Same thing, mix up and use a dressing, preferably olive oil based. I think you get the idea. Run a couple simultaneously and all you have to do is go to the fridge and spoon it out. Take some time for yourself, probably on a Sat or Sun when yournot busy w/daycare and make a couple up. Another tick I use is to buy stuff frozen and already individually portioned, but I shop at Sams or Costco where it is readily avail, cheap. I haven't been in the commissary recently, but you should be able to do the same things. No reason for defrosting, they'll cook up great on one of those Foreman type of grills. Also, it sounds like I might be down on grains, I actually am not, I just use a lot of quantity control. I make a fairly large pot up of quinoa, barley, rice or bulgar wheat up fairly regularly. Pull or portion for family use, then put the rest in the tupperware type of containers with enough to last a day or two or three. Keeps very well in the freezer, and reconstitues very nicely and quickly in freezer, and holds in the fridge for up to a week. Bulgar and cousous are even easier, no cooking required. Same goes for legumes. My favorite are lentils, and I usually mix them w/ quinoa, save a portion of the mix in the fridge, the rest in the freezer. The only thing is portions w/ thee mixe. I use 1/4-1/3 cup as a serving for breakfast, or take a spoon or two over the top of veg salads. Potatoes are simple, but the little red or wasx new or fingerlings. They microwave up eaily. Just remember portions. Use one or two every now and then. Just a few tips on how to have stuff readily avail so that you don't have to make a big production out of every meal. I brown bag to work, just stuff the things in ziplocks and tupperware. When I get home, I go to the freezer, pull out a piece of frozen fish, throw it on Foreman, or pull out a ziplock that I've had something marinated in since morning and throw it on the Foreman,then go into preprepared salads. Done in ten minutes w/ no "fast food".
Hope this gives you a few ideas.
