You can just put whatever vegetable you want in with the pasta as it cooks - broccoli, green beans, zuccini, crookneck squash, spinach.... drain, put in some olive oil, red pepper flakes, a can of tuna or salami - or if you are close to camp when you shop, you can get ham, turkey, whatever from a deli counter at the grocery if you're lucky. I always carry olive oil, salt, pepper, red pepper flakes. Parmesean cheese stays good in your pannier for a long time, too - especially if you buy a block, not grated.
