With Spring coming soon, the foraging bug has bitten again. For any FLDGers who may share this pastime, here is an interesting page. There are undoubtledly many such resources available online.
The very weeds that sprout in your lawn, like dandelions and chickory, were purposely brought to the United States by our immigrant forefathers as edible plants.
Italians, along with the Greek and Spanish, are one of the few western cultures that continue to forage for wild food to this day. Any culture which has had to face hunger and famine took to explore the "wild" for edible plants. The Italians, in particular, have a history of foraging that goes back to Roman and, even, Celtic origins.
