How to understand "You're one to talk".
The following is from "FRIENDS".
(Joey found his father had some kind of relationship with another woman so he was annoyed. During cooking.)
Joey's father: You are burning your tomatoes.
Joey: You are one to talk.
How to understand "you are one to talk"? The Chinese subtitle means "You don't want to change subject", but I don't think the translation is proper. So I need native speakers' explanation. Thank you.
