Pesto is a good way to use almost any type of greens or herbs. If you have access to foraged nettles, try this recipe that uses a superfood wild edible green.
Heat oven to 300°F. Rinse nettles in a colander and let drain. Place walnuts on a rimmed baking sheet. Bake until lightly toasted and fragrant, about 12-15 minutes.
Shake the colander to remove excess water from the nettles.
Process nettles, spinach, olive oil, garlic, lemon juice, salt, and walnuts in a food processor until finely chopped but some texture remains, stopping once to scrape down the sides.
Thin with water as needed. Makes about 1 cup.
Refrigerate up to 1 week or freeze up to 3 months.
