• 2  teaspoons  minced garlic
• 3  tablespoons unsalted butter

Directions

1. In a saucepan sweat the celery, carrot, onion and garlic in the butter, covered with a buttered round of waxed paper and the lid, over moderately low heat for 5 minutes. Add the flour and cook the mixture over moderate heat, stirring, for 3 minutes.
2. Add the gravy, and stock, cook over moderate heat, stirring for 5 minutes. Add turkey, peas, carrots, pearl onions, salt and pepper to taste, and bring the mixture to a simmer.
3. Transfer the mixture to a flameproof 1 1/2-quart baking dish, and with a spatula spread the stuffing over it. Drizzle the stuffing with some melted butter. Bake the pie in a preheated 350 oven for 30 minutes, or until bubbling, and put it under a preheated broiler until the top is golden brown.
