Combine veal, pork, breadcrumbs, eggs, onion, chopped parsley, garlic powder, salt, and pepper; mix well. Shape meat mixture into a loaf; place in a lightly greased 13- x 9- x 2-inch baking dish. Bake at 350° for 20 minutes.
Pour water over loaf, and bake an additional 40 minutes. Remove veal loaf to a warm platter; garnish with cherry tomatoes and parsley, if desired.
Note: This loaf is delicious served hot as well as when served cold on whole wheat bread with Dijon mustard.
