Should my[20M] girlfriend[19F] apologize for accidentally hurting my feelings? 2.5yrs

Girlfriend of 2.5 yrs. Each at different universities 80 miles apart. She is a sophomore, I'm a junior.

This morning we had just started our hw skype. I had sat down with my breakfast in front of her and was telling her how I was disappointed how it had turned out. I explained that the fake bacon I had used (I live with my brother and SIL who eat veg) tasted really bad and when I used the same skillet for eggs they were also bad.

She replies by giggling and telling me that, "I told you that fake meat is bad news from the devil." Apparently this is a quote from a recent Two Broke Girls that she thought I had seen. I hadn't.

I know that she thinks eating veg is silly and all hippie. I'm in between on the subject.

I am upset and tell her that she has hurt my feelings. She thinks that she doesn't have to apologize because she was only trying to joke and make me feel better.

Am I right in asking her to apologize for accidentally hurting my feelings?

TL;DR My girlfriend upset me when she was trying to make me feel better with a joke and doesn't think she has to apologize because her intentions were right and it was an accident.
