Ok, so this should not be made with spaghetti. I really don't understand why the author of this recipe would suggest it. Soba noodles are the right noodle for this recipe.
Also there needs to be some more green in this. The carb-to-veggie ratio is pretty terrible. I'm thinking of maybe adding some chinese cabbage
Once you switch out the spaghetti for soba this is a pretty nice recipe. It still needs some tweaking though.
