How about a Vietnamese cooking class for your husband? He can learn how to make his favorite dishes and pick up new recipes to try at home. Alternatively, you could consider getting him a Vietnamese cookbook by a well-known chef or food writer so that he can explore new recipes and ingredients at his own pace. Another idea could be taking him out to a high-end Vietnamese restaurant for a special meal.
Or you can get him a star map with the date when he was born.
