Pesto is my favorite thing in the entire world. I can eat varying iterations depending on the season and I do. In fall, I make kale pesto; in winter, I love beet-green pesto; and during spring it’s all about asparagus pesto. It may seem a bit strange to pulse up a beautiful vegetable like asparagus and coat it with pasta but I promise you it’s delicious. I like to include a bit of spinach to balance out the asparagus—it adds a nice freshness to it. In this pesto, you’ll see many of the usual suspects: Parmesan, olive oil, garlic and salt and lemon. For this recipe in particular, I favor pistachios (green on green!) but feel free to swap it in with pine nuts or almonds.
