Bring a pot of water to a boil and cook the ramen noodles according to the package directions; drain well and set aside.
Heat the sesame oil and olive oil in a very large skillet or wok over medium-high heat until shimmering.
Add the diced chicken and cook for about 4 minutes, stirring or flipping intermittently, until the pieces are nearly cooked through.
Add the broccoli florets, diced red bell pepper, drained baby corn, and drained bamboo shoots to the skillet; cover and steam for 3 to 4 minutes until the vegetables are crisp-tender.
Uncover, add the cooked noodles, soy sauce, rice vinegar, chili garlic sauce, and ground ginger; toss everything together and cook 1 to 2 minutes until heated through and evenly coated.
Remove from heat, sprinkle with sliced green onions and optional sesame seeds, season with salt, pepper, or extra soy sauce to taste, and serve immediately.
