Here's the story...
A few days ago, our friends, Evan and Lisa, brought us a big, beautiful bag of basil from their garden. I knew right away that I would be making pesto ASAP. We had just run out of parmesan and I didn't have any pine nuts, so I went to Costco the next day to get what I needed. As you probably know, pine nuts are not cheap. Like $25 for not-even-that-big of a bag. So I went out on a limb and decided to try walnuts instead. It was a success!! We loved the walnut pesto! Give it a try and see what you think.
