1 cup fresh breadcrumbs made from crustless french bread
Position rack in bottom third of oven and preheat to 450°F. Mix together mustard, mayonnaise, and 1/2 of green onions in small bowl.
Sprinkle chops on both sides with salt, pepper, and allspice. Heat oil in heavy medium skillet over medium-high heat. Add veal; sauté until brown, about 2 minutes per side. Transfer veal to small rimmed baking sheet. Add garlic to drippings in skillet; stir 15 seconds. Add breadcrumbs; sauté until golden and crisp, about 1 minute.
Spread half of mustard mixture thickly atop each chop. Spoon crumbs atop mustard mixture. Bake until thermometer inserted horizontally into chops registers 135°F for medium-rare, about 7 minutes. Transfer to plates. Sprinkle with remaining green onions.
