Vegan Tzatziki Pasta Salad

1 The cashews for the sauce need to be pre-soaked. I like to soak mine overnight. I just start soaking the night before I know I am going to make this. However, they need to be soaked for at least 3-4 hours. Or if you are in a pinch you can soak them in boiling water for 15-30 minutes. 
2 Once you are ready to make the pasta salad, cook the pasta according to the package instructions. 
3 While the pasta is cooking, make the tzatziki sauce. Drain the cashews you soaked, then add them to a blender or food processor. Then add the almond milk, olive oil, lemon juice, cucumber, garlic, dill, salt and pepper. 
4 Blend on high, scraping down the sides as needed until the sauce is really nice and smooth, it may take a few minutes. 
5 Once the pasta is done, let cool for a little while. Then add the pasta to a large mixing bowl. Then add the olives, sun dried tomatoes and artichoke hearts. Then pour the sauce on top. 
6 Toss everything together so the pasta is completely coated in the sauce and the veggies are evenly distributed. Serve immediately, or place in the fridge to serve cold later.
