I've had a burger every day since. I just ruined another dish I used to be able to eat out.
"Chopped" is a misnomer. At first I'd slice as far as I could, then some final mincing with a chopping motion. I've come to think of even that as mashing the meat. After slicing along all three axis, one can wad together the meat and slice another pass or two, as if slicing salumi. No thwacking the knife on the board, all careful drawing the knife past the meat.
It is worth a try. Nevertheless, one of my favorite scenes from "Being John Malkovitch" is the documentary clip where Sean Penn struggles with whether he should follow John into puppetry.
