Serving: Makes about 1 1/2 cups
You will need: a baking tray, a mortar and pestle (pictured). If you don't have a mortar and pestle, you can use a blender or bowl and the head of a rolling pin as an alternative.
Preheat the oven to 400°. Toast the nuts on a baking sheet for about 4 minutes, or until lightly browned.
Coarsely chop the basil leaves. Combine the basil and garlic in a mortar and pound to a coarse paste using the pestle. Add the nuts and pound again until smooth. Stir in the Parmesan and or Pecorino, then 3/4 cup of the olive oil. Transfer the pesto to a bowl and season with salt and pepper to taste!
Enjoy on zoodles (zucchini noodles), salad wraps, omelettes, meat, or anthing that is improved by sauce!
