For extra flavor, use the sun-dried tomato oil that comes in the same jar as the sun-dried tomatoes. If not available, substitute with olive oil.
If using chicken thighs (bone-in, skin-on) adjust the cooking time to 8 minutes. For boneless skinless chicken thighs, pressure cook for 5 minutes.
You can substitute the heavy cream with half and half, but the sauce will be thinner.
For some extra sauce, double the whipping cream, and parmesan cheese amounts.
Freshly grated parmesan cheese will result in a smoother sauce.
