Nice job- I like the idea of the double pan. I’m partial to not-very-lean chopped meat, and meatloaf in a pan does tend to seem like it’s treading water in grease (there’s a messed-up metaphor!).
My best friend’s mom always put the hard-boiled egg in her meatloaf; I do it once in a while when I remember. She was Brooklyn jewish, though, not Italian; we New Yorkers tend to overlap & share our traditions. My other best friend’s Italian mom always made extra eels on Christmas eve, just for me.
