When you think of pesto, you probably think of fragrant, summer basil. I did too, until I figured out how to always have fresh pesto by using herbs and greens that are seasonal.
Place pine nuts, garlic, spinach, parsley, sage, nutritional yeast and salt in a food processor. Pulse until finely chopped. With the processor on, add in lemon juice then drizzle in olive oil until the desired consistency is achieved. Taste and adjust seasonings.
