You wonder what the phrase "easy as pie" means, because pie crust is extremely hard to make, amirite?

As easy as eating pie? Assuming you aren't allergic or whatever eating pie is pretty easy

I actually know this!
In fairs they used to often have competitions for prizes, and the lowest prize was often a slice of pie.
Easy to win!

Pie crust is actually really easy to make, the simpler recipes only have four ingredients.

I think it is suppost to mean easy as eating pie? Or something? Anyway I just buy it from the store.
