Cool, that's nice of you. Basically, Thanksgiving isn't a present giving holiday. That's not to say you couldn't give one to be nice. But, generally, it's a time to stop and give thanks for what you have. Her Thanksgiving may be different, so you may want to ask her how she usually celebrates, but the general way would be with a big Turkey dinner. Turkey (some people have ham, too, I think?), stuffing, cranberry, various vegetables (peas, corn, carrots, green beans, etc. etc.), mashed potatoes, sweet potatoes, gravy, etc. etc. (Not all of that necessarily, hehe, we usually just have Turkey and 3 or 4 of the rest). Pumpkin pie is pretty common for a dessert. I'm sure others can speak to what they usually have, but again, it may be a good idea just to ask her. You could even do it in an innocent way like "Thanksgiving? We don't really celebrate that over here. How do you celebrate it?" that sort of thing. That might get the best result. Again, nice idea.
