one thing is pasta.
a box of angelhair, a jar of pesto. dry goods.
a box of fettucini, a 1/2 pt. whipping cream, some garlic, a wedge of parm.
very compact. butter. oops, i forgot about that.
spaghetti, a can of tomato sauce or your favorite kind of canned tomato, some dried herbs like basil, oregano, a little salt, etc., plus garlic for a quick sauce. fridge-free.
peanut butter sandwiches! cereal! just keep a quart of milk available.
you might try shopping daily?
canned beans cooked with some ham, and some red pepper flakes or hot sauce, plus a big hunk of buttered Italian bread, would make a great dinner. filling and delicious.you can buy a 6-pk. of eggs instead of a dozen.
meat is flat and can be stored in a small space.
as for drinks, buy cans or indicidual bottles and put a few in at a time.
that's all i can think of for now.
i believe that life would not be complete sans comfy 'ol tee-shirts, the Golden Girls, and the color pink
& rock on, PITTSBURGH-
