Is it permissible for a non-Muslim spouse to consume/eat haram thing while married to a Muslim?

In an interfaith marriage, we know what Muslims can and cannot eat (i.e halal only). For the practicing Christian woman, whilst she has stopped drinking alcohol (in fact, never really drank alcohol but only on special occasions), she has also or is trying to give up eating pork items. The question is: in such a marriage/situation, can the Christian woman eat some pork items even though she is not Muslim and provided the Muslim man keeps things separate, is this allowed/permissible (of course, ensuring Allah SWT is not angry/mad at the Muslim)? We are talking about things like salami or pepperoni. She can eat and keep it separate but in such a marriage, is it possible/allowed?
