Kale Pesto (in 5 minutes!)

In a large food processor fitted with an "S" blade, combine the kale leaves, walnuts, lemon juice, garlic, salt, olive oil, and 1/4 cup of water. Blend until smooth, stopping to scrape down the blender, as needed. 2. Taste the pesto, and adjust the flavor and texture to your liking. For a smoother pesto, add up to 1/4 cup more water. For more flavor, you can add 1/4 teaspoon more salt, to help compensate for the lack of Parmesan cheese. (Or if you want to add Parmesan cheese to this, use only 1/2 teaspoon of salt to start with, and add more to taste, after adding the cheese. See notes.) 3. Once the flavor and texture are to your liking, you can use this pesto on pasta, pizza, and more. Store any leftovers in an airtight container in the fridge for up to 3 or 4 days. 4. Bring a pot of salted water to a boil, and prepare the noodles according to the package directions. Once the pasta is done cooking, drain it and set aside. (You can prepare the pesto sauce while the pasta is cooking.) 5. Using the same pot you used for the pasta, heat the olive oil over medium-high heat. Saute the onion and tomatoes until softened, about 5 minutes. Add in the cooked noodles and prepared pesto sauce, and toss until heated through. Serve warm. 6. prep5 mins 7. cook15 mins 8. total20 mins
