Whisk the sauce ingredients in a small bowl. Set aside.
In a large, deep skillet, heat the avocado oil over medium-high heat, about 2 minutes. Add the frozen vegetables, the garlic and the ginger. Cook, stirring often, until the veggies are defrosted and tender, about 5 minutes.
Reduce the heat to medium. Give the sauce another stir, then add the turkey meat and the sauce to the skillet. Cook, stirring, until everything is well-coated and the sauce thickens, about 2 minutes.
Transfer the turkey stir-fry to a serving platter. Drizzle with the sesame oil and scatter the scallions on top. Serve immediately.
