First, get ready to boil your pasta by adding water to a large pot. Add a few pinches of salt, turn the heat to high and bring to a boil. Add pasta once boiling and cook per instructions on the package.
Now, start on your breadcrumbs. Note: if you don't plan on making homemade vegan breadcrumbs, I still highly recommend adding store bought Italian breadcrumbs as it's an integral part of the dish! Place 2 slices of bread in the toaster and toast well. You want this brown and crispy, but not burnt. Wait for the toast to cool.
Once the toast is no longer warm, break it up in small pieces and add it to your high speed blender. Blend until you have breadcrumbs!
Empty the breadcrumbs from your blender (you should have around 3/4 - 1 cup of breadcrumbs) and add the remaining breadcrumb ingredients. Stir, taste test, and set aside. Done! Next, make your walnut pasta sauce.
First, toast the walnuts. Simply add your cup of raw walnuts to a pan and turn the heat to medium. Do not add any oil. Stir frequently for about 5 minutes, until the walnuts become fragrant and you see the them browning slightly.
Next, add all of the walnut pasta sauce ingredients to the blender and blend on high until it's smooth and creamy. Taste test and add more seasonings/nutritional yeast if desired. I didn't go TOO heavy on the seasoning in this vegan walnut pasta sauce because the breadcrumbs add a TON of flavor, but add more flavor to your liking!
Once the pasta is done, drain and return to the pot. Add the walnut pasta sauce to the pasta and stir well over low heat. Next, add in your fresh chopped kale and stir again. Serve when the pasta is heated throughout.
Plate the pasta and add a generous portion of breadcrumbs (so good!) and top with additional parsley. Enjoy!
