Prepare rice noodles by soaking or cooking according to package instructions, then drain and rinse with cool water to prevent sticking.
In a small bowl, whisk together soy sauce, oyster sauce, sesame oil, rice vinegar, honey, sriracha, garlic, and ginger; set aside.
Heat 1 tablespoon of oil in a large skillet or wok over medium-high heat, then add chicken or tofu and stir fry until cooked through, about 5 to 6 minutes; remove and set aside.
Add remaining oil to the skillet, stir fry bell pepper, broccoli, carrot, and onions until crisp-tender, about 3 to 4 minutes.
Return cooked protein to the skillet, add drained rice noodles and sauce, then toss quickly until well coated and heated through, about 2 to 3 minutes.
Serve divided on plates or bowls, garnished with sliced green onions, sesame seeds, and lime wedges if desired.
