Cook the noodles according to package instructions. Drain and set aside.
In a large skillet or wok, heat the vegetable oil over medium heat. Add the minced garlic and ginger, sautéing for about 1 minute until fragrant.
Add the sliced bell peppers, carrots, and snap peas to the skillet. Stir-fry for about 3-4 minutes until the vegetables are tender but still crisp.
In a small bowl, whisk together the soy sauce, sriracha, sesame oil, honey, and rice vinegar. Pour this sauce over the sautéed vegetables and stir to combine.
Add the cooked noodles to the skillet, tossing everything together until the noodles are well coated in the sauce and heated through, about 2-3 minutes.
Remove from heat and stir in the sliced green onions. Serve hot, garnished with sesame seeds.
