Cut bells peppers, red onion, and chicken into thin strips and add to the Instant Pot

Combine chili powder, salt, cumin, oregano, paprika, cayenne, black pepper, and garlic powder in a small bowl

Pour the chicken broth into the spice mixture and combine fully

Pour the broth and spices into the Instant Pot and stir to combine all the ingredients

Close the instant pot and set the vent to sealing

Set the Instant Pot on manual for 8 minutes - the IP will come to pressure (about 10 minutes) and then cook

After 8 minutes of cooking at pressure the Instant Pot will beep. Manually release the pressure and remove the lid

If you want a slightly thicker sauce set the Instant Pot to saute and combine 1/2 tbsp of arrowroot starch with 2 tbsp of warm water, pour the mixture into the Instant Pot while stirring the fajitas

Continue stirring for a minute or so as the sauce thickens

Turn off the Instant Pot and enjoy on tortillas, rice or cauliflower rice
