I'm kind of a spinach addict. It goes in almost everything I could, and I eat it as a salad and in green smoothies daily!

My spinach pesto recipe:
2 Cups Baby Spinach Leaves
Handful of Flat Leaf Parsley, about 1/2 cup
4 – 5 Large Basil Leaves
1/2 cup Walnuts, lightly toasted
3 Garlic Cloves, peeled
1/4 teaspoon Salt
Pinch of Freshly Ground Black Pepper
3 Tablespoons Extra Virgin Olive Oil
Pile everything but the oil into a food processor and combine well.
Using a spatula, scrape the sides then reattach the lid.
With the motor running, drizzle in the oil through the feed tube one tablespoon at a time until everything is smooth but not oily. You may only end up using 2 tablespoons. (Use the remainder for topping the pesto, if you’re keeping it in the fridge.)
Pesto may be kept in a sealed container, topped with oil. Otherwise, it freezes very well in ice cube trays or flattened, in a ziploc bag, where you can break off desired amounts for soups, crustini or pasta for one.
I like to add a bit of parmesan cheese when I add the pesto to the pasta/raveloli/rice/potatoes etc.
Yields about 1 Cup.

The nice thing about pesto is you can make any substitution you can think of. No walnuts? Try pecans, or pine nuts, or cashews! No basil? Try fresh thyme, or rosemary or any other herb you love! Pesto rocks!!!
