All veggies that are noted to be sauteed should be sauteed separably, for about a minute or so, just to loosen up a bit and bring more color, sweetens and to add one more layer of flavor. Use sesame seed oil or any oil on hand if you desire, but I think that sesame seed oil gives very unique flavor. Also, always season it with a drizzle of soy sauce, or sea salt and pepper if you do not have any soy sauce-season just enough to taste. Also, I use soy sauce, light which has less sodium.
