Preheat oven to 400°.
Heat oil and butter in a large nonstick skillet over medium heat. Add onion and shallots; cook for 6 minutes or until tender, stirring frequently. Add peas and wine, and cook 2 minutes. Add turkey, parsley, and sage. Combine broth and flour in a small bowl, and stir well with a whisk. Add broth mixture to pan; bring to a boil. Cook 1 minute, stirring constantly. Stir in salt and 1/8 teaspoon freshly ground black pepper.
Combine the remaining 1/8 teaspoon pepper, mashed potatoes, and cheese in a small bowl. Spoon turkey mixture evenly into each of 6 (8-ounce) ramekins coated with cooking spray. Top each evenly with the potato mixture. Place ramekins on a baking sheet. Bake at 400° for 20 minutes or until lightly browned and bubbly. Let stand for 8 minutes before serving.
