Prep basil and lemons: Start by washing fresh basil leaves under running water or submerging them in a bowl of water and shaking them to remove any dirt. Use a salad spinner to dry leaves or lay them flat on a plate or kitchen towel to dry.
Blend ingredients: Toss the cleaned and dried basil in a food processor with lemon zest and lemon juice. Next, add nuts or seeds and garlic cloves. Pulse until finely chopped, slowly drizzling in olive oil until the chopped ingredients are well coated in oil but still chunky.
⅓ cup pine nuts, 2 cloves garlic, ½ cup extra virgin olive oil
Add seasonings to finish: Finish by adding in the cheese (or nutritional yeast), salt, and pepper. Give the pesto a taste and add more seasonings until it's flavored to your liking.
