I have a 16" ceramic/cast iron paella pan from Copco many years ago and it fits perfectly on my large BGE. Also have a 24" that fits on an Xlrg but the handles get in the way to close the dome. Sits up about 1/2 " from full close but works great. Target probably never heard of a BGE. The pan should look like a paella pan 1 1/2-2" deep sloped sides and metal. Just 'cause it says stove top should not be a problem.
My 16" cooks for 6-8 folks depending on sides and libations.
