Begin by unwrapping the ramen noodles and discarding the seasoning packets. In a medium pot, bring 6 cups of water to a boil over high heat. Add the ramen noodles and cook for about 2 minutes until they are just slightly chewy. They’ll finish cooking in the sauce later. Drain and rinse the noodles under cold water, then set them aside.
Heat a drizzle of oil in a large skillet over medium-high heat. Add chopped chicken and vegetables to the skillet and sauté for 8 minutes, or until the chicken is fully cooked and the vegetables are tender. Once done, remove from heat and add the cooked ramen noodles to the skillet.
In a small bowl, mix together the cornstarch and 2 tablespoons of water, then set it aside.
In a separate small pot, whisk together all of the sauce ingredients. Bring the sauce to a boil, then reduce the heat to low. Stir in the cornstarch-water mixture and let it simmer for 3 minutes, stirring occasionally, until the sauce thickens and coats the back of a spoon.
Pour the sauce over the noodle mixture in the skillet. Toss everything together until the noodles and chicken are evenly coated in the sauce.
Return the skillet to medium-high heat and cook the mixture for about 3 minutes, allowing the noodles to become tender and absorb the sauce.
For an extra touch, garnish with sesame seeds and chopped scallions, if desired.
Serve hot and enjoy!
