Put spagetti on plate and spoon sauce over it.
You can be very versitile with this recipe. I don't use garlic and onion because it doesn't agree with me, but I'm sure they would be delicious. Also you can make as much vegetables as you want and add a larger amount of sauce to make this for more people. Sometimes I saute chunks of tofu with the vegetables. You could also add a yellow pepper to make this very colorful. We love this dish and I hope you enjoy it too.
