i've always carried a small bottle of red wine vinegar and a matching bottle of olive oil while on a hike/trek/rove.
dandelions, miner's lettuce, fireweed, chickory flowers, etc, tossed with vinegar, oil, salt and pepper. feel free to garnish with crushed cranberries, raspberries or blackberries as they are available. if you find almonds, acorns, or walnuts, feel free to shell and chop and add(if you're really gung ho, you'll have a lump of bleu cheese to crumble into this, and then we're having real fun), along with whatever else you like.
just because we're in the wilderness doesn't mean we can't eat civilized food, i always say. the salad, by the way, goes well with my next favorite.
my other big living off the land food be rabbits. mm. this year i'll try my hand with my .36 cal navy revolver, but in the past i just used my .357 magnum loaded with .38 special or shotshells(depended on the rabbit). a slow lead round knocks them top over teakettle just fine. aim high to avoid gutshooting. a sharp loud whistle will stop them in their tracks and make them pop up if you need a better shot.
grill them, roast them, steam them(if you have a big enough pot), wrap them in big moist fern leaf bundles and bury them under a fire, have fun.
