What just happened?

So all day yesterday i was feeling fine. I ate breakfast and so on. Around 5pm i went to stepmoms family member grad party. They are arabic and tend to cook arabic food. I never really tried it before. Then around 10 pm i started to feel neaseas. My grandparents brought home McDonald's and i was barely able to eat cause i felt so sick. Around 12 am i woke up and vomited. And after i did I felt fine. What could of caused me to puke? Food poisoning? Something i ate?
