Radish Greens Pesto

In a food processor, combine the pine nuts, garlic, salt, and pepper and pulse until well chopped. Add the lemon juice and pulse again.

Add the radish greens and basil and pulse until combined.

With the food processor running, drizzle in the olive oil and pulse until combined. Add the Parmesan cheese, if using, and pulse briefly to combine. For a smoother pesto, add more olive oil.
