Somebody Help This Poor Girl: Austria Meets Dallas

What would you do if the following scenario was your life?

My Austrian foreign exchange student’s parents are coming here at the end of May.  I want to have a going away party for the student and combine it with a welcome to Texas party for the parents. I can’t decide what to do.  A taco truck would be fun, but don’t have the names of any.  Or should I do BBQ, is that more quintessentially Texas? I can’t spend a bunch of money. I am amenable to having it catered at my house or at a restaurant.  Any suggestions?

I am no longer a caterer and my heart rate doubles when I read this, so you guys help her.
