Preheat your oven to 375 degrees F and grease a 9x11 baking dish.
Prepare the sauce by whisking together all the sauce ingredients until smooth, then set it aside.
Place the ramen bricks in a bowl and cover them with boiling hot water. Let them soak until soft, then drain well.
Transfer the cooked ramen to the baking dish. Add broccoli, chicken, green onion, and peanuts on top.
Pour 3/4 of the sauce over the ingredients in the baking dish and gently toss to coat.
Sprinkle with salt and pepper, then bake for about 35 minutes, or until the chicken is cooked through.
Broil for an additional 2-3 minutes to finish.
Remove from the oven, plate the dish, and drizzle with the remaining sauce. Add extra green onions and peanuts if you like. Enjoy your meal!
