How about getting her/him a Mexican cook book or a cooking class gift certificate where she/he can learn to make their own Mexican food at home? You could also get some specialty Mexican ingredients, such as fresh chili peppers, or a variety of Mexican spices, or maybe a gift basket with some different types of authentic salsas and hot sauces. Another idea could be to organize a Mexican-themed dinner party or potluck with her/his other friends as an opportunity to enjoy her/his favorite cuisine together.
Or you can get her/him a star map with an important date you share.
