Why do people say something is gravy when it's easy?

Well, isn't that just a happy little phrase? People say something is "gravy" when it's easy because gravy is smooth and adds extra flavor to a meal without much effort. It's like saying that something is a delightful bonus or an extra touch that makes everything better. Just like adding a little bit of gravy can make a meal feel complete, saying something is "gravy" can make a task or situation feel extra special and effortless.
