vocab for the week 25

Is it okay to say ‘prepare the vegetables’? 

I understand this is an expression commonly found in recipe books. When you ask someone to prepare the vegetables, what you would like the person to do is to wash them, clean them, peel them, and cut them. In other words, the person ensures that the vegetables are ready to be used.
*Maya, you’ll have to prepare the potatoes. I want you to peel them and then cut them into thin slices.
