Student Exchange Programs

So theres a girl in my school who is a foreign exchange student…and we thought it be cool to invite her out to eat with us next weekend. Well long story short, she said she would come. Soooo, my question is, what are some things I can say to/ask here to keep the conversation going smoothly. I just don’t want it to be awkward.
P.S. I know this is kinda a stupid question, because there are a ton of things I could say to her, I just wanna have a big list in the back of my mind so theres not any awkwardness…thanks!
