To make the chili oil. Heat a large skillet over medium heat. Add the peanut oil, garlic, ginger, and chili flakes. Cook, stirring occasionally until the garlic is fragrant, 5 minutes. Stir in the sesame seeds, cook 30 seconds to 1 minute more. Remove from the heat and very carefully transfer the oil to a heat proof bowl or glass jar.

Meanwhile, cook the eggs noodles according to package directions.

Combine the soy sauce, vinegar, honey, chili paste, and 1/3 cup water in a bowl.

Place the skillet over medium high heat. Add the chicken. Season with black pepper and brown all over, breaking it up as it cooks, about 5 minutes. Add the red and green onions, and cook another 2-3 minutes. Slowly pour in the soy sauce mixture and add the bok choy. Bring the mixture to a simmer and cook until the sauce coats the chicken, about 3-5 minutes.

Stir in the noodles and 2 tablespoons chili oil. Remove from the heat. Serve the noodles warm, topped with additional chili oil and green onions. Enjoy!
