Place the leaves of coriander and basil into your food processor.

Chop leaves for about 10-20 seconds on high.

Stop processor and add cashews, garlic, 2 tbsps parmesan, salt and pepper.

Process all the above together on high while slowly adding a stream of olive oil until desired consistency is achieved, I prefer a nice thick pesto, however depending on the use you may want to have it a little thinner.

Once desired consistency is achieved add a few drops of sesame oil to taste.

If not being used right away place in an air tight container with a thin layer of olive oil over the top of the pesto.
