lots of pasta lol. sometimes you can find generic brands of pasta on sale for like $1 or .50 cents. Stockup like a months worth. Tunafish, pb and j, ramen noodles. Buy a pack of chicken breasts in bulk and eat them slowly over the whole month. Try and consolidate trips in the car so youre not burning uneeded gas. just drink water for a month, no beer or soda or gatorade. hope some of that helps lol. and congrats! germany sounds like fun!
