Bring several cups of water to a boil in a medium sized pot. Add in your pasta, reduce heat to medium, and cook until Al Dente, about 8-10 minutes.
Meanwhile, make the sauce by placing the garlic cloves, lemon juice, and olive oil into a food processor. Process until smooth. Now add in the pitted avocado, basil, and salt. Process until smooth and creamy.
When pasta is done cooking, drain and rinse in a strainer and place pasta into a large bowl. Pour on sauce and toss until fully combined. Garnish with lemon zest and black pepper. Serve immediately.
