In a mortar and pestle (or food processor) crush the basil, spinach and nuts until they are starting to blend and breakdown. Add the garlic, horopito and cheese and grind a little more.
Drizzle in the oil slowly to combine all ingredients until your mixture starts to resemble pesto. Add the salt and pepper and mix. Taste. Add more salt and/or pepper until your tastebuds start dancing for joy.
Serve with fresh focaccia bread and store in an airtight container in the fridge.
