It is a phrase that may have two or more meanings depending on the intention with which is diga.1) if it says in a friendly and helpful tone means that they put to your orders and provision what you know and want to share their knowledge on how to cocinar.2) if it says as an epithet (derogatory) then means that the only for what they serve is to be cooking and nothing else. You could probably have more meanings but these two are that I can think of at this time.
