A main course of sautéed veal, sauced with a bit of mustard, white wine, and cream, can be ready in minutes. Use your favorite mustard to personalize the dish.
Heat the butter and oil together in a large skillet over low heat. Add the scallions and cook for 5 minutes without browning.
Raise the heat, add the veal, and season with salt and pepper. Cook the veal for 1 minute per side; do not overcook, and do not worry if it does not actually brown. Remove the veal from the skillet and keep warm.
