Every festive season I love having easy and simple appetizers such as this vitello tonnato recipe which can be prepared in advance. It's delicious and can be used with thinly sliced veal, roast turkey or something similar.
Start by making the tuna sauce. Place all the ingredients in the bowl of a stick blender (or use a food processor) and blend until smooth. Season with salt and pepper to taste.
Take a nice large plate or divide it immediately over four plates. Place the slices of veal on each plate and cover generously with the tuna sauce.
Sprinkle with capers and any fresh herbs you like, such as garden cress.
