Roasted peanuts on grill?

I swear I saw a recipe on here where you took dry roasted peanuts and coated them with barbecue sauce and then roasted them on the grill? I have the peanuts coated with sauce and on a sheet of aluminum foil, but now I'm not sure if I'm supposed to wrap the foil around them or leave them open to dry? Plus, I've searched but can't find the recipe.

Has anyone done this that can tell me how to finish these?

Thanks.
