Set the instant pot to 'Sauté' mode and add olive oil.
Sear the chicken thighs skin-side down for 4-5 minutes until golden brown.
Flip the chicken and sear for another 4-5 minutes.
Remove the chicken and set aside.
Pour in the chicken broth and scrape the bottom to deglaze the pot.
Add the mixed vegetables to the pot.
Place the chicken thighs on top of the vegetables.
Close the lid, set the valve to 'Sealing,' and cook on high pressure for 10 minutes.
Allow for natural pressure release for 10 minutes, then quick release the remaining pressure.
Garnish with fresh herbs before serving.
