I posted this yesterday but CH folks said it belonged in Not About Food section. Since that is such a broad area and most folks outside of Mid Atlantic (or even Trenton!) have heard of a Tomato Pie, I wanted to alert you to look for this topic on the Not About Food Board.
Don't reply here or it will be considered "off topic" and it will be pulled. And you'll miss the Map of Trenton Tomato Pie places!
