Add all of the pesto ingredients to a food processor, starting with 1/4 tsp salt.Pulse until combined, scraping down the sides of the processor bowl as necessary before blending again. Add a little water as needed during the blending process to achieve the desired consistency for your pesto (thick for spreadable, thinner for a sauce).Taste and add more salt if desired.Note: If your pine nuts/sunflower seeds are not already toasted then add them to a dry (no oil) frying pan. Toast them over low heat, stirring occasionally, until lightly golden - this should take around 10 minutes.Note: If you are using toasted sunflower seeds, they can take a little longer to break down in the food processor than pine nuts so make sure to blend for long enough to create a smooth sauce. 40 g pine nuts or sunflower seeds, 60 g fresh basil leaves, 7 g nutritional yeast, 50 ml olive oil, 3 small cloves garlic, 1/2 tbsp lemon juice, 1/4-1/2 tsp salt, 1/8 tsp ground black pepper, up to 40 ml of water to loosen the mixture, if you’re using sunflower seeds also add 1/4 tsp dried rosemary
