Heat 1 tablespoon of sesame oil in a large skillet over medium-high heat. Add the ground turkey and cook, breaking it up with a spoon, until it is no longer pink.
Add the garlic and ginger to the turkey and stir for 30 seconds until fragrant.
Push the turkey to one side of the skillet. Add the remaining tablespoon of sesame oil along with the broccoli, bell pepper, and carrots. Cook the vegetables for 4 to 5 minutes, stirring occasionally, until they begin to soften.
Stir the turkey and vegetables together. Add the cauliflower rice, soy sauce, and rice vinegar. Cook for another 3 to 4 minutes, stirring often, until the cauliflower rice is heated through.
Remove the skillet from the heat. Sprinkle the green onions and sesame seeds over the top before serving.
