How about a gift certificate for a BBQ class where your wife can learn new techniques and recipes? Another idea could be a personalized set of BBQ tools with her name engraved on them. If she doesn't have one already, you could also consider getting her a high-quality smoker or grill she has had her eye on. Finally, a subscription to a BBQ magazine or membership to a local BBQ club could be an excellent gift for her.
Or you can get her a star map with the date of your anniversary.
