We are from Tennessee, and you are 100% correct. We eat it as an appetizer sometimes, as well, with toothpicks and some quality mustards of our choice. Our alma mater sells it at the baseball concession stand.
Seacrest Sundries had it on our menu for a couple years. Not many takers down here! So we did away with it. But it was soooo good, we hand sliced a big thick piece, fried it up on white bread with onion & mustard. Ummmm, now I'm craving one!
