In a medium bowl, combine soy sauce, honey (or maple syrup), rice vinegar, grated ginger, and minced garlic. Whisk together until smooth to make the teriyaki sauce. Set aside.
Heat sesame oil in a large skillet over medium heat. Add the ground turkey, breaking it up with a wooden spoon. Season with salt and pepper. Cook until browned and fully cooked, about 5-7 minutes.
Add the broccoli and bell peppers to the skillet with the ground turkey. Stir-fry for 3-4 minutes until the vegetables are tender but still crisp.
Pour the teriyaki sauce over the turkey and vegetables. Stir to combine and cook for an additional 2-3 minutes until the sauce is heated through.
To serve, spoon the cooked brown rice into bowls and top with the teriyaki turkey and vegetable mixture.
Garnish with chopped green onions and sesame seeds.
