Years ago my wife gave me a book about wild foods one can pick and eat, and I tried a lot of the stuff in it. As I recall, everything I tried was nasty. With dandelion leaves, you are supposed to pick the littlest, tenderest leaves... and eat them as salad. They're not too too bad. Also recommended were plantain leaves; again you pick just the youngest, tenderest ones and you have to cut them across the leaf to sever the long fibers... I did not like them.

Mushrooms can be good, but you really have to know what you're doing.

Violets --the flowers, that is-- are very good on a salad. The deep purple (violet) colored ones taste like green peas. The white ones with a purple-pink blush in the center taste more like bubblegum. We tried the yellow ones too, but couldn't get enough of them to really taste anything at all!

Nasturtiums are good to eat as well; you can eat both the flowers and the leaves. They have a sharp kick, like radishes. But I've never seen them growing wild.

Raspberries, blackberries, mullberries, juneberries, blueberries, mmmmmmmmmmm....
