Bring a pot of salted water to a boil; add the noodles and cook as the label directs. Reserve 1 1/4 cups of the cooking water, then drain and rinse the noodles. Transfer to a large bowl and toss with 1 teaspoon sesame oil. Mix the oyster sauce and vinegar in a cup; set aside.

Heat 2 tablespoons vegetable oil in large skillet over high heat. Add the eggplant and stir-fry until golden, about 2 minutes. Add the mushrooms and cook until wilted, 1 minute. Push the vegetables to one side and add the remaining 1 tablespoon vegetable oil. Add the garlic and cook 30 seconds. Add the turkey and stir-fry until cooked through, about 3 minutes. Stir the turkey and vegetables together; add the scallions and half of the oyster sauce mixture and cook 1 more minute.

Add the noodles, 1 cup of the reserved cooking water and the remaining oyster sauce mixture and 1 teaspoon sesame oil. Stir-fry until heated through, 1 to 2 minutes, adding more cooking water as needed to loosen. Top with cilantro and serve with Sriracha, if desired.
