Combine the pesto ingredients in a blender until thoroughly combined and set aside.
Preheat the oven to 400 F and line a large baking sheet with parchment paper
Place all of the sheet pan ingredients on the pan and evenly space them, not to overcrowd the pan (see notes). Evenly coat the chicken and vegetables with the pesto, reserving some of the pesto on the side for later topping if desired.
Place in the oven and periodically flip the veggies every 10 minutes or so to evenly bake. Bake for 30-35 minutes, or until chicken reaches an internal temperature of 165 F.
Remove from the oven and top with additional pesto if desired before serving.
Notes
Be sure to not overcrowd the pan
