Toast nuts, stirring frequently, in a dry skillet over medium heat until lightly golden. If you are a “nut-burner,” just skip this step and put them in the food processor raw. Remove from heat and allow to cool. If you're using sunflower seeds, just use those raw.

Place nuts and garlic in the bowl of a food processor fitted with the metal blade and process until very finely chopped.

Add kale, basil, salt, pepper and lemon juice and pulse until chopped.

With the food processor running, add olive oil in a steady stream until you achieve a smooth texture. Add cheese and process until well combined.

Taste for seasoning and add additional olive oil to make a looser pesto.
