My grandson is visiting and wanted to try some wild greens. Here was the meal we came up with.
This meal exposed the weakness of romantic thinking of "living off the land." Our meal was good, but it would have been far less pleasing without the butter to sauté the fronds, the butter, flour and milk for the soup, the olive oil for the salad, and good old salt and pepper.
Living off the land takes a lot of planning--more than a year ahead. Fat is the most difficult to come by unless you kill an animal and render the fat, or collect many, many nuts. We have lots of hazelnut (filbert) trees, but in the ten years we've lived here, I could count on one hand the number of nuts I've seen. The jays and squirrels take them all.
It's fun to know edible plants, but don't think you can feed yourself easily from what you find.
