Graham, that's not meatLOAF mix but meatBALL mix. Anyone who watches cooking programs knows that Pork/Beef/Veal is the holy trinity for a good Italian meatball. So yeah, possibly it's a NY (/tri-state area) thing.
@BIKEFOR1: THE LABEL ON THE PACKAGE CLEAR SAYS "MEAT LOAF". PERSONALLY, I LIKE MY MEAT LOAF WITH PORK/BEEF/LAMB; BUT LAMB IS KIND OF EXPENSIVE SO I USUALLY JUST USE BEEF/PORK.
No wonder Rachael Ray mentions this product all the TIME. I had to dig to find veal at Fred Meyer recently - although now I see it all the time, of course.
