Sprinkle turkey with salt and pepper. In a large nonstick skillet over medium heat, brown turkey in oil on all sides. Cover and cook until a thermometer reads 165°, 10-12 minutes. Remove and keep warm.
Combine cornstarch and juice until smooth; add to the pan. Stir in the steak sauce, preserves and lemon juice. Bring to a boil; cook and stir until thickened, about 1 minute. Slice turkey; serve with sauce.
