Good morning! We don't have to forget that besides growing our own plants, there are many edible plants that grow by themselves in the fields. Including here near a town where I live, there's plenty. I just went for a walk and picked some nettle, then a few leaves of plantain and a big leaf of common comfrey to add to our veggie pot. There's a lot of mallow as well. Of course, always be sure of what you collect!
