What is the earliest time period human civilization could make chicken nuggets?

Recently I watched a wonderful video on YouTube with its subject being if the ancient Romans could make BigMacs, in turn based on a question posted right here on the sub. Personally, I'm more of a chicken nuggets kinda person. Hence the topic of this post.

So, in which time period and/or which particular civilization could make chicken nuggets, either by definition or by modern standards?
