I had this at a polish restaurant one time. They called it the hunter’s stew - bigos. That dish apparently has a million variations that look different than this, though. I’m not polish so I could be completely wrong here.

!WetBeardHairs is spot on with it being a traditional Polish dish. I’m very unsure of the recipe, but I’ll happily postlude the location of the restaurant (Poland) if it doesn’t violate any rules and if it does and you are still interested message me and I’ll tell you there! (:

(Apparently I do not know how to tag a user in a post like I thought I did haha please feel free to point me in the right direction)😅
