In a small sauce pan, steam the sweet potato chunks until tender, about 10 minutes. Mash the cooked potato with a fork, then measure out one cup of mashed sweet potato for the sauce.
Add the one cup of mashed sweet potato to your blender, along with the rest of your sauce ingredients, then blend on high, until smooth and creamy!
Adjust the seasonings to taste, then serve over a bowl of your favorite piping-hot pasta!
