Bring a large pot of salted water to a rolling boil over high heat. Add your favorite pasta and cook according to the package directions until al dente, typically around 8-10 minutes. Once cooked, drain the pasta in a colander and return it to the pot, allowing any excess water to evaporate.

Drizzle in a small amount of olive oil and stir through. Toss in a few ice cubes, stirring gently until they melt to cool the pasta.

In a food processor, combine the ripe avocado, garlic, fresh herbs, white wine vinegar, and optional nutritional yeast. Pulse until smooth and creamy.

Once the pasta has cooled, add it back to the pot along with diced spinach and green onions. Pour the dressing over the mixture and toss gently.

Garnish with sliced green onions and serve chilled.
