I am keenly aware that some people have an issue with veal. And even if you don't, veal isn't the easiest thing to find at a typcial grocer. Thankfully tonnato sauce is just as delicious served with pork. I prefer pork tenderloin, but it is equally as tasty on a chop. I've also been known to smear it on toasted bread as an aperitivo.

My favorite recipe is from Marcella Hazan, found in the Essentials of Classic Italian Cooking. I've tweaked it a bit for efficiency (store bought mayo is fine ;).
