Bring a large pot of water to a boil. Generously salt the water and add the pasta. Cook the pasta to al dente according to package instructions. (Cook according to the lower end of time for best results)
While the pasta is cooking, combine all of the Lemon Basil Vinaigrette ingredients into a blender or food processor. Blend until smooth. Transfer into a small bowl or jar and set aside.
Gather the veggies for the salad. Chop the cucumber, tomatoes, red onion, avocado, and basil.
When the pasta is finished, drain the pasta in a colander and rinse the pasta with cold water to stop the pasta from cooking any further.
Transfer the pasta into a large bowl. Add all of the veggies, chopped basil, and feta cheese to the pasta. Top with the Lemon Basil Vinaigrette and mix well. If time permits, cover the pasta salad and place in the fridge for at least 1 hour.
Top the pasta salad with fresh ground black pepper, more feta cheese, and dill/parsley. Enjoy!
