Preheat oven to 375°. Combine first 8 ingredients in a small saucepan; bring to a boil. Cook 8 minutes or until reduced to 1 cup. Combine mushroom mixture, mustard, and pepper in a large bowl; stir well. Stir in breadcrumbs; let cool slightly.
Crumble veal over mushroom mixture; stir just until blended. Pack mixture into an 8 x 4-inch loaf pan coated with cooking spray. Bake at 375° for 50 minutes or until meat loaf registers 160°. Let loaf stand in pan 10 minutes.
Remove meat loaf from pan; cut loaf into 12 slices.
Note: Ground turkey or chicken can be substituted for ground veal.
Sandwich suggestion: Serve leftover meat loaf slices on kaiser rolls with herbed mayonnaise and lettuce.
