Melt the butter in a large skillet over medium heat and add the garlic, cooking 30 seconds until fragrant.
Add the ground turkey, breaking it apart, and cook until browned, about 5-6 minutes.
Stir in the rice, chicken broth, and soy sauce, scraping up any browned bits.
Bring to a simmer, cover, and cook 15-18 minutes, until the rice is tender and liquid is absorbed.
Stir in the frozen peas and carrots and cook 2-3 minutes more, until heated through.
Season with salt and pepper, top with green onions, and serve.
