I am so sorry you are having this problem. I am lucky (and not so lucky) that no one tries to cook for me. I think that if I was faced with this, I would try a few things a) I would speak to them and ask their support and understanding. b) I would try to be patient and understanding. c) If it continued I would simply get up and fix myself a salad or something else to eat. Eventually, they will get the idea.
