Spray the bottom of the pot with olive oil cooking spray.
Place the chicken on the bottom of the pot or use the wire rack.
Add the veggies around and on top of the chicken to fit.
Pour the chicken broth over the entire dish to add some liquid to the pot.
Evenly pour the pesto sauce over the chicken.
Lock the lid in place and set the nozzle to "seal."
Press the pressure function to manual pressure on high for 25 minutes.
Once it goes off, quickly release the steam by moving the nozzle to "vent", release all steam.
Check the chicken to be sure it's fully cooked.
Serve.
Notes
This can be made with the wire rack and the chicken and veggies around it on the wire rack if you prefer. We typically place it just in the bottom of the pot, but it's totally up to you.
The veggies are going to come out VERY soft, so if you like them crispy, you may want to air crisp them instead after the chicken is cooked.
If you prefer you can also sear the chicken in the bottom of the pot with the saute function before pressure cooking to get it browned a bit on the outside.
