My wife's into hiking. Over the years she learned from other hikers about wild edibles. There are tons of wild edibles here. In a week or two, she'll be coming home from hikes with bags and bags of all sorts of wild eats.
The fist time she cooked for me she made this unbelievable wild edibles salad - topped with this wild raspberry and wild onion dressing she makes.
During summer she'll take trips down to the ocean where she gathers beach greens. Every summer the same people are out there harvesting down at the beach. People who don't know about wild edibles don't know what they're missing. It's a good, healthy hobby.
