Bring 2 cups water to a boil in a medium saucepan, add the wild rice and a pinch of salt, reduce heat to medium-low, cover, and simmer until the water is absorbed and the rice is tender (about 1 hour 20 minutes for traditional wild rice; check package instructions).
While the rice cooks, combine soy sauce, white vinegar, 1 tsp sesame seed oil, peanut butter, honey, garlic powder, and sriracha in a blender and blend until smooth; stir in 3–4 tbsp hoisin sauce and set the sauce aside.
Heat 1 tbsp sesame oil in a large skillet or wok over medium-high heat.
Add the chopped onion and sauté 8–10 minutes until softened and starting to brown.
Add the chopped red and green bell peppers, cover, and sauté about 4 minutes until they begin to soften.
If using raw turkey or chicken, add it now and cook until mostly browned, about 4–6 minutes, then add the green beans.
Add the chopped green beans, cover, and sauté 6–8 minutes until the beans are tender-crisp.
If using already cooked turkey, add the chopped cooked meat now and heat through for 1–2 minutes.
Pour 3–4 tbsp of the prepared hoisin-peanut sauce over the stir-fry and toss to coat; adjust amount to taste and ensure any raw meat is fully cooked.
Serve the stir-fry over the cooked wild rice in bowls.
