Preheat oven to 350 degrees.
Cook noodles according to instructions.
In a 13x9 casserole dish, mix 1 jar spaghetti sauce with cooked noodles.
Sprinkle on top oregano, basil, marjoram, garlic (whatever Italian spices you prefer - I make this blend myself and this is what I usually use for Italian seasoning).
Cover with foil, bake for 20 minutes.
Uncover, sprinkle 2 cup shredded vegan cheese on top. Bake for 10 minutes uncovered.
Serve.
(I usually serve this with bread, salad, and some kind of fruit to make up for its somewhat lacking nutritional content. Use whole-wheat noodles if you prefer them, but they do have a somewhat tougher texture.)
