Cook the pasta according to the package instructions. Then, strain and set aside for later.
While the pasta is cooking, make the tahini sauce and cook the veggies.. To make the tahini sauce, add all of the sauce ingredients including the tahini, water, lemon, salt, and pepper to a blender or food processor and blend until smooth. While the sauce will be semi runny, it will thicken up as soon as you add it to the pasta later.
Next, add the vegan butter to a large sauce pan or skillet and heat until melted. Once the butter has melted, add in the shallots and garlic and saute for 2-3 minutes. Then, add in the shaved brussels sprouts and saute over medium heat another 8-10 minutes.
Once the brussels are cooked and beginning to crisp, add in the white wine, salt, and pepper. Stir everything together and cook over medium heat another 2 minutes.
As a final step, add in the cooked pasta and tahini sauce and mix everything together over low heat an additional 2-3 minutes. If your sauce is too thick, add in extra water. If it is too thin, just heat it a little longer until it thickens.
Serve with a garnish of optional fresh parsley and a lemon wedge. Enjoy!
