Bring a pot of water to a boil then let it simmer until needed.
In a small bowl, whisk together ingredients for the sauce. Set aside.
In a large skillet, heat up 1-2 tablespoons of vegetable oil over medium-high heat then add the diced chicken. Season with salt and pepper and brown on all sides until mostly cooked through, about 5-7 minutes.
Add the baby broccoli and cook to desired doneness. I like mine with a bite so I don't cook mine very long especially since they are chopped so small.
Pour the sauce into the skillet then let simmer until thickened, about 3 minutes. Turn the heat down.
Bring the pot of water to a rolling boil then add the ramen noodles. Cook until done, about 3 minutes.
Add to the skillet then toss everything together until noodles are coated in the sauce.
