In a small bowl, whisk together rice vinegar, hoisin sauce, soy sauce, and brown sugar until well combined; set aside.
Spray a large frying pan with nonstick cooking spray and place on the stove top over medium-high heat.
Add ground turkey and minced garlic to the pan.
Sprinkle the garlic salt, pepper, and onion salt over the meat.
Add half of the liquid mixture to the pan so the juices cook in with the meat.
Cook the meat, breaking it up, for about 15 minutes or until fully cooked through.
Set the meat aside, and place the green beans and mushrooms into the pan and drizzle the olive oil over it.
Cook until the mushrooms are a shiny brown and the green beans soften and reach desired tenderness.
Add the meat back into the pan and pour the rest of the liquid mixture over the meat, mushrooms and beans.
Cook until the juice is well incorporated.
Serve over cooked rice.
