  • I used a marinara sauce for this recipe, but any tomato based pasta sauces will work well in this recipe.
  • You can use any sausage in this recipe or other ground meats like beef, chicken or turkey.
  • Quick release the pressure for this recipe. Take care when removing the lid as it will still be very hot.
