How about getting him a BBQ tool set? You can include a personalized message or his name on each individual tool, making it extra special. Another option could be a BBQ cookbook or a set of different BBQ sauces and rubs from different regions to try out on the grill. For something more unique, you can book him a class or experience where he can learn how to smoke and prepare meat in new and exciting ways.
Or you can get him a star map with the date of your anniversary.
