Reminiscent of pesto, this creamy sauce opts for avocados for some of the usual olive oil, and includes plenty of fresh parsley and lemon for brightness. It makes enough to cover 8 ounces of pasta (you can go with spaghetti or another favorite shape). Before draining the pasta, set aside 1/2 to 1 cup pasta water to toss in with the sauce in case you'd like a looser texture. While the sauce on its own is vegan, mixed with pasta, it's excellent topped generously with freshly grated Parmesan and additional chopped parsley. The recipe is a Yummly original.
