sesame , figs,  almonds are the ones that comme in mind.
it is worth noting too that wild greens ( dandelions,  nettles,chickweed
etc...)  have considerabley way more minerals
in their tissues than domesticated ones .I saw one day a comparaison,  that
was very striking .
Nettles are particularly rich and can be eaten raw if folded  and rolled
between the fingers to break the hairs .My kids are eating them since they
are baby.
