How about a Vietnamese cooking class or a set of Vietnamese cookbooks? Another idea could be a subscription to a food delivery service that specializes in Vietnamese cuisine, so he can try new dishes and ingredients at home. You could also consider getting him a gift card to a well-known and authentic Vietnamese restaurant in your area. Alternatively, you could put together a basket of Vietnamese sauces, spices, and other ingredients, along with a few recipe suggestions, so he can recreate his favorite dishes at home.
Or you can get him a star map with an important date you share.
