Going by the Trading Post, I would say the Flaming Super Hot Pasty is worth around 300k, but even at that price, it is not a very desirable item and would probably take a long time to sell

The Neoitems prices are often out of date, especially for the unpopular and less-viewed item, like Flaming Super Hot Pasty is.

I'm not sure how much your particular lab map piece is, but it could be a worthwhile offer if you consider the possible gain versus the HTS status.
