Homemade Walnut Pesto

So we LOVE pesto in our house. I decided I would give it a shot to make it myself. I was pleasantly surprised with the way it turned out.
Here's how I made it:
2 Cups of Spinach
3 Tablespoons of Olive Oil
1/2 Cup of Walnuts
Basil to Taste (I used 4 leaves)
2 Cloves of minced garlic
A couple of pinches of salt and pepper
That's seriously it. Simple ingredients and so EASY!
I made this in my food processor. I added all the ingredients and then let it go until it was the consistency I liked. Now, we like our pesto thick and not real runny, but if you want it thinner just add some more olive oil to it.
