Preheat oven to 350°. Sprinkle veal with garlic, 1/2 teaspoon salt and pepper. In a large skillet, brown veal in 2 tablespoons butter on both sides. Transfer to a greased 13x9-in. baking dish.
In the same skillet, saute onions and mushrooms in remaining butter until tender. Stir in cracker crumbs, cream, wine or broth and remaining salt; cook and stir until mixture comes to a boil. Stir in parsley; pour over veal.
Cover and bake 20 minutes. Uncover; sprinkle with cheese. Bake 5 minutes or until cheese is melted.
