If the pasta is sticking together at all, rinse it under cool water until it separates, then give it a shake to remove any excess water.
Toss the pasta in a large bowl with the chimichurri sauce and 2 tablespoons of olive oil. Taste and season as needed. You can also add another tablespoon or two of olive oil if it needs additional moistening. Serve immediately or keep covered in the fridge for up to 4 days.
