In a small bowl, whisk together the soy sauce, honey, rice vinegar, and sesame oil.
Heat a large skillet over medium-high heat and add the ground turkey, cooking until browned and crumbled for approximately 5 to 7 minutes.
Add the minced garlic and ginger to the skillet and sauté for 60 seconds until fragrant.
Pour the prepared sauce mixture over the turkey and stir to combine.
In a small ramekin, mix the cornstarch and cold water to create a slurry; pour into the skillet.
Simmer the mixture for 2 to 3 minutes until the sauce thickens into a glossy glaze.
Divide the cooked rice and steamed broccoli among four bowls.
Top each bowl with the teriyaki turkey and garnish with sliced green onions and sesame seeds.
