Set the Express Crock to sauté on high. Add the oil, allowing to get hot before adding the bell peppers, onions, and celery. Cook until the vegetables have softened.
Stir in the sausage and chicken, cooking until the chicken has turned white on the outside. Stir in the remaining ingredients (reserving the parsley for garnish).
Add the lid, turning to the locked position. Make sure the steam release value is set to sealed.
Turn the rice/risotto setting to high for 8 minutes. The Express Crock will take about 10 minutes to heat up and build pressure, during this time the display will say “HEAt” (yes, with a lowercase “t”). Once the 8 minutes have finished, turn the steam release valve to open (careful, the steam is hot!). Allow the steam to release before opening the Express Crock.
Ladle into bowls, top with parsley.
