Rub tenderloins with olive oil and season with sea salt, set aside.

Pour the vinegar in a ceramic baking dish that is just large enough to hold all the tenderloins in a single layer, and place butter in the center of the dish.

Transfer the dish to a warm oven.

Place a grill pan over medium high heat on the stove.

Grill the veal on each side for 3 to 4 minutes for medium rare.

Remove ceramic dish from oven and place grilled veal in the balsamic butter, turning to coat each piece.

Allow veal to rest in dish for 5 minutes before serving.
