Consuming them is another possible form of control! :D

Throughout my amateur culinary career, I found that plants considered weeds in some countries, are often staples in the cuisine of another. Examples are buckwheat (used to be considered bird feed in Cyprus, where I live, but regular food in many countries and now most of the world, including Cyprus), purslane (one of our best Cypriot national salads is made with it), and common mallow (we fry it with eggs and, again, it's one of our favorite national dishes).
