Wild guess: Chenopodium or Atriplex of some kind. These are usually
around a foot or foot and a half or so tall and are common weeds of
cultivated ground and some are grown/used to be grown for medicinal or
culinary purposes. The most famous has the unlikely name of
Chenopodium bonus-henricus or Good King Henry.

Goosefoot is pretty well-known, too - and edible.

Not a very good fit to your leaf but possible?

As you say, there are many others. Pictures of the plant and more
of the leaves (and preferably flowers) would help.
