Should I ask her if she’s wants breakfast?

So classes start tomorrow and I (21f) just moved into student housing. I have one roommate (20f) I met yesterday and we haven’t talked much outside of the official meeting. She had friends over and seemed preoccupied. I’m new to this school and state so I have no friends at the moment. I wanted to order McDonald for breakfast since it’s the only thing in this small town and I’m yet to go grocery shopping. Should I ask her if she wants to add to the order? Or is it too soon? Thanks
