Bring a large pot of salted water to boil.
In a medium sized mixing bowl, add in seasoned breadcrumbs, yogurt, egg, nutritional yeast, shallot, parsley, garlic, salt, oregano, and black pepper and mix until well combined.
While meatballs are cooking, add in your dry pasta and cook until al dente according to your box instructions. Drain pasta (not too much, a little excess pasta water is great to add to the sauce!) and add into the meatballs and sauce. Gently toss until spaghetti is evenly coated with sauce. Top with optional fresh basil!
