Kickin' Kale Pesto
The pesto will stay greener longer if the lid/plastic wrap over it's container is directly over the top, not allowing the pesto to have contact with the air.
Most pesto recipes call for Parmesan cheese, but for a stronger flavor, I like Romano cheese. You can also substitute walnuts for pine nuts. If you can't stand the heat, you definitely don't have to use the habanero-infused olive oil.
For more flavor toast your pine nuts first!
