I was craving a light and savory pesto one summer night, but didn't want to run to the store for the only missing ingredient: pine nuts. This recipe is a combination of different pesto recipes. The lime juice livens this pesto up in an interesting way. I like to use this pesto for pasta, but it easily takes the place of any classic pesto. I also use it for a topping on eggplant sandwiches, a spread for wraps, or a dip for pizza or veggies.
