The truth is that if you lack the confidence then no one here can help you. Like if I were to give you 5 good sentences, you would be out of luck after you ran through all of them and you'd be screwed. And if you had the confidence then no one here can help you because you don't need the help since it will flow naturally. My advice is to not take suggestions on what to say, but instead you should work on confidence. Once that is fixed, you won't need to think about what to say...it'll come on its own.
But if you want to say a few sentences to her, ask her if she likes eggrolls and wantons and whatever else. Pretty sure all asians love those things.
