How about a Greek cookbook with traditional recipes? You could also package it with some Greek spices or ingredients to get her started. Another idea is to arrange a cooking class where she can learn how to make traditional Greek dishes with a professional chef. You could also consider getting her a Greek wine or a set of Mediterranean-themed kitchen towels or apron.
Or you can get her a star map with an important date you share.
