Bring a large pot of salted water to a boil and cook the lo mein noodles until just al dente. Drain and toss with a small drizzle of toasted sesame oil to prevent sticking.
In a small bowl, whisk together soy sauce, honey, oyster sauce, rice vinegar, sriracha, black pepper, and the cornstarch mixed with water.
Heat vegetable oil in a large skillet over medium-high heat. Add chicken thighs in a single layer and cook until golden and cooked through.
Reduce heat slightly and add garlic, ginger, and the white parts of the green onions. Cook just until fragrant.
Pour the garlic sauce into the skillet and simmer, stirring gently, until thick and glossy.
Add the cooked noodles and toss until everything is well coated. Finish with toasted sesame oil.
Garnish with the green parts of the green onions and sesame seeds. Serve warm.
