get a skillet with a little oil. and put mixed veggies in it.
once tender, add soy sauce. not to much...then after its cooked in to veggies, remove and put aside.
get another skillet and fill half way with water. and a little oil and salt to keep from sticking.
once it starts to boil stick your spaghetti noodles in the skillet and cook til almost tender and add soy sauce a little at time. once noodles are tender and have barely and liquid, add in your veggie mixture and stir together add a little extra soy sauce to keep from burning and let cook til there is no more liquid. serve and enjoy.
