Plenty more where that came from

The idiom plenty more where that came from is something you say when you have given out some of something, and there's a large supply of more of it.

The phrase has been used in everyday English for many years to emphasize abundance. It suggests that what has just been given or shown is only a small part of what is available.

She handed out a plate of cookies and said there were plenty more where that came from in the kitchen.
