Wash a lot of Spinach!
Chop up some walnuts
Mince some Garlic (or use a handy dandy garlic press!)
Toss the ingredients into a blender or food processor
Drizzle in some Olive Oil (I also added just a bit of water)
Add some Salt and Pepper to taste
Blend away! Until it reaches a nice pureed consistency!
Mix it with some Pasta, or use it as spread on a burger, or anything else you can think to put it on...
