This is the closest to the stainless steel mesh they used that I could find

Insert bun (this is from the local Albertson's)

T-t-t-t-toasty!
NOTES:
1) I'm not so sure that's stainless steel so we didn't eat the bun (we tossed it all).
2) If I had made the form so the bun was closer to the grill (shorter), it would have cooked the bun sooner.
3) At this height, it was almost too dry by the time it got to the desired state of toastiness
