This is literally ~the easiest~ one bowl shoyu udon or soy sauce noodles recipe that was actually a spur-of-the-moment creation since I just had a short break from work and wanted a satisfying noodle dish.For this One Bowl Shoyu Udon or Soy Sauce Noodles, I used instant fresh udon noodles that I keep in the fridge. These noodles are in vacuum-sealed packets and are already cooked so I just soak them in some hot water to carefully separate these and cook them down a bit more. I mixed in all the sauces and seasonings before mixing some sliced tofu in and TA-DA! I had a hearty meal in minutes.
