To make the sauce, add the avocado, garlic paste, heavy cream, grated Parmesan, and lemon juice to a food processor. Blend until smooth, then taste for seasoning - adding salt and pepper as necessary.

Heat some olive oil in a large skillet and add the zoodles. Sauté them for just a few minutes, then season them with more salt and pepper. Serve the zoodles and top it with the sauce and garnish with fresh herbs.
