Healthy spaghetti from Nanny's Pavillon, I ordered this because I was curious, but then I found out it wasn't as good as I expected although all my friend said it was delicious, but hey maybe you should try it.

3 cups tightly packed fresh basil leaves (2 ounces total)
3 tablespoons walnut pieces
3 tablespoons grated Parmesan cheese
2 garlic cloves, peeled
1 tablespoon fresh lemon juice
coarse salt and ground pepper
3 tablespoons extra-virgin olive oil

In a food processor, combine basil, walnuts, Parmesan, garlic, lemon juice, and 3 tablespoons water, season with salt and pepper. Puree until a paste forms. With motor running, add oil in a thin stream. Process until very smooth, about 1 minute.
