Remove chicken quarters from sealed package and place on a large sheet tray covered in parchment paper. Distribute the chicken evenly across the tray (skin side up) so that they are not touching each other.
Mix 1/4 c. of vegetable oil with the Chinese Five Spice Powder in a medium bowl. Using a basting brush, coat the tops of the chicken quarters with the spice mixture.
Roast in a 400ºF oven, until the skin begins to crisp and an internal temperature of 145ºF is reached.
Place all of the vegetables in a large mixing bowl and add the remaining vegetable oil, sesame oil and season with salt and pepper. Toss and distribute evenly across a large sheet tray covered in parchment.
Roast at 400ºF for 6-8 minutes, until vegetables come lightly browned around the edges.
Place chicken and vegetables on top of rice and serve.
