Heat & Prep: Preheat your oven to 350°F. In a small bowl, whisk together the sesame dressing, peanut butter, soy sauce, and red pepper flakes. Set this "liquid gold" aside.
Sear for Flavor: Spray a large ovenproof skillet with cooking spray and set over medium heat. Sear the chicken thighs for about 3 minutes per side until golden brown. Remove the chicken and keep it covered on a plate.
Sauté the Veggies: In the same skillet, add the bok choy, onions, and peppers. Sauté over medium-high heat for 3 minutes. Stir in the ginger and cook for just 30 seconds more until it smells incredible.
Assemble for the Oven: Nestled the chicken back into the skillet on top of the vegetables. Pour the peanut sauce evenly over the chicken and veggies.
Bake: Cover the skillet (use foil if you don't have a lid) and bake for 25 minutes, or until the chicken reaches an internal temperature of 165°F.
The Finish: Serve the chicken and tender vegetables over a bed of brown rice. Top with sliced green onions and chopped peanuts for that essential weekend crunch.
