I'm hoping someone could help me identify  this please.

It's a small triangular shaped plate with a painted onion, a capsicum (?) a jar of ..., and some parsley (?), it has a wooden handle that can be unscrewed and a Kasuga Ware Japan sticker on the base.

I've been looking for similar online but obviously I'm not looking in the right place because I can't find anything. I'm not even sure what is, maybe a condiment plate for the table.

Thank you
