In a large skillet or wok, heat the olive oil over medium-high heat.
Add the ground turkey to the skillet, seasoning with salt and pepper. Cook for about 5-7 minutes, breaking it up with a spatula, until browned and cooked through.
Add the minced garlic and ginger to the skillet, cooking for about 1 minute until fragrant.
Toss in the broccoli florets, sliced bell pepper, and snap peas. Stir-fry for approximately 3-5 minutes until the vegetables are vibrant and slightly tender.
Pour in the teriyaki sauce, stirring to coat the turkey and vegetables evenly. Cook for an additional 2-3 minutes until everything is heated through.
Remove from heat and sprinkle with sesame seeds and sliced green onions for garnish.
