Cube your chicken thighs and add it to the pot (you can use 2 chicken breasts cubed if you prefer).
Add your onion, celery, green beans and all of your spices. Stir until well combined.
Add cabbage cut into chunks on top of this chicken/spice mixture (don't fill pot more than 3/4 of the way full, I have a 6 qt. and 1/3 of a head was about what would fit, larger pots you could add a bit more).
Pour chicken broth on top. If you are making chicken quinoa casserole use 1 3/4 c. broth, if you're making chicken cabbage soup add 2-2.5 c depending on how soupy you want it.
Push the poultry button on your Instant Pot and adjust the time to 12 minutes.
Do a quick release.
Open lid and add 1 c of uncooked traditional quinoa, stir.
Close lid, close steam valve, and set to pressure high for 1 minutes.
Allow for a 13 minute natural release so the grains can fluff up and get nice and tender. Release rest of pressure and fluff before serving.
