How about a Spanish cookbook? You could also consider a cooking class to learn how to make some Spanish dishes together. Another idea could be a gift certificate to a Spanish restaurant in your area so you can both enjoy a meal out. Additionally, you could put together a gourmet basket with some Spanish ingredients such as olives, cheeses, and chorizo.
Or you can get her a star map with an important date you share.
