In a small bowl, whisk together ingredients for the sauce. Set aside.
Heat a large skillet over medium-high heat with olive oil for turkey. Once hot, add turkey and the white and light green parts of the green onion. Cook the meat until browned—about 5 to 7 minutes, stirring occasionally. Carefully drain out any liquid.
Return skillet to the heat and stir in garlic. Sauté for about 30 seconds until fragrant.
Pour in sauce and stir, cooking for another minute until warmed through and bubbling. Remove from heat.
