If someone offered you free vegetables and beverages for the taking all summer long, would you accept them? Most of us would. Free vegetables would help tremendously with ever rising grocery bills and with hot weather, free cold beverages would be quite welcome!
Now I'll give you a clue. If you have used chemical fertilizers or weed killer on your lawn, you can't have them. They might still be there, but they're not safe to use.
I'm talking, of course, about wild foods. As in, those weeds you fight every summer. Dandelions, amaranth, salsify, lambsquarters, purslane and mallow are some of the most common back yard "weeds" that are not only edible, they often surpass their garden cousins in nutrition. Some of them are the ancestors of vegetables we enjoy today. Some of them are considered delicacies or at the least, unusual, and come at a high price at uptown grocery stores.
Cold beverages can be made from the leaves of strawberries, raspberries, blackberries and mint of any kind just like you would make tea.
They're free; they're good and they're good for you. What more can you want?
