How about a personalized grilling set? You can get a set of utensils engraved with his name or initials. Or, if he already has a set, you could get a personalized BBQ apron or tool belt. Another idea is to get him a digital meat thermometer or grill thermometer, so he can monitor the temperature while he's cooking. You could also consider getting him a cookbook specialized in grilling recipes or a subscription to a grilling magazine. Lastly, if he doesn't have one already, a high-quality grill brush or grill cleaning tool could be a useful and appreciated gift.
Or you can get him a star map with the date when he welcomed you in this world.
