Rinse the basil leaves off and remove the leaves from the stems. Set the leaves aside.
Add pine nuts, garlic, lemon juice, salt and nutritional yeast to a small food processor or small blender and pulse until roughly mixed.
½ cup pine nuts, 3 cloves garlic, ½ lemon, ¼ teaspoon salt, ¼ cup nutritional yeast
Add the basil leaves to the food processor and pulse. Drizzle in the olive oil while it's running. Add some water if needed for desired consistency. Stop the food processor occasionally to scrape down the sides.
2 cups fresh basil, ¼ cup extra virgin olive oil, 2-3 tablespoons water
Taste and add more salt if needed. If it's too acidic, add more nutritional yeast, if it's too thick, add more olive oil or a splash of water.
