Meanwhile - boil water for pasta. When pasta is done reserve some of the pasta water (about 1-2 cups). Mix pasta in with the veggies. I cooked the whole box but only used about 1/2-3/4 of it cooked. Saved the rest for another time.
For the sauce - in a mixing bowl, whisk together 3-4 tablespoons tahini, 2 lemons (juiced), and add this to the veggie pasta mixture. As you stir, add in some of pasta water so the sauce gets creamy and can mix well with everything - you want it to thin out a bit so you have more.
Once everything is mixed and looks creamy, add to serving bowls and top with more spices for garnish (parsely, paprika, salt, and pepper).
Finally, top with some chopped walnuts for crunch.
