Next, add the heavy cream stirring to combine
Turn down the heat to low and add the parmesan cheese
Stir in the spinach until wilted
Next, return the chicken, chicken sausage, and any juices that have settled on the plate to the skillet and let simmer until well combined and the chicken is 165 degrees
