Start cooking by adding about 3 1/2 cups of water in a pan, add to this about 4 cubes or 2 tablespoons of chicken stock and mix well. Cut the spam, sausages and tofu into slices and cut all the vegetables. In a bowl add all the ingredients for the sauce and mix well. Place the sauce into the pan and add the other ingredients around it, keep the noodles on the side for now.
Bring the entire mix to boil and cook well, this should take about 15 minutes, the easiest way to check is to see if the onion is soft. At this point add some noodles. It is recommended to use some instant noodles like Shin Ramyun, or you could use any supermarket ramen noodles. This will take a further 3-5 minutes to cook.
Serve in a bowl and enjoy, there should be plenty for up to 5 people and you could serve with rice and some side dishes if you like, however with the noodles there is enough to fill you up.
