Bring a large pot of salted water to a boil and cook the pasta according to package directions. Make sure to reserve about 1 cup of the pasta cooking water before draining the pasta.
While the pasta is cooking, whisk together the tahini sauce ingredients in a bowl until smooth and creamy (or use a blender or food processor). Add just enough of the water to form a smooth and creamy sauce (amount will depend on thickness of tahini used).
Toss the drained pasta together with the tahini sauce to evenly coat. Gradually add some of the reserved pasta water until you have a creamy, silky sauce coating the pasta.
Serve the pasta immediately (the sauce will thicken as it cools). Garnish and enjoy!
