No Rsvp, no dietary accomodations?

I have a friend who is a notorious no show to events. She is also a vegan, so when she comes to an event there are always accomodations to be made for her diet. We had a party where we catered food and had to get additional items for her that were vegan friendly. She cancelled the day before. It was only a $14 loss, but it was still something we specifically made sure to work around for her. She has no showed at multiple parties/get togethers for our circle of friends, even when she says she is coming. She hasn't RSVPed for our celebration party or returned the follow up call. She is the only vegan we have. Is it ok for me to not order food for her from the caterer? Part of me feels guilty that she will literally have nothing to eat except fruit if she shows up because all of our dishes are prepared with butter or have meat and cheese in them except the fruit. The other part of me says that if she wanted to be accomodated she should have sent the card back or called. I have to put the final order in on Monday and am planning on not ordering the servings of vegan friendly items because it will be part of our final food total and nobody else will eat it. I'm being ridiculous, I can handle being told.
