Corned Beef and Cabbage Soup-Stew

OK...so it's not a Japanese dish but this one pot meal came in to existence because of some time constraints. I started the flat cut corned beef in a large pot with plenty of water and on a low flame early in the morning. Normally, I'd pour off the water and begin with fresh. The main reason why I didn't is because there was no spice pack. So I just added the cleaned potatoes, carrots and cabbage to the pot. Now I generally find the vegetables in corned beef and cabbage to be a bit tasteless. My answer to this problem was to add a fair amount of vegetable base to the pot as well. The final ingredient to be added to my soup pot was german style egg noodles since I didn't want to have a second pot of water on my stove.
All in all, while the concoction does sound a bit weird it tastes pretty good. I'm starting to think of another way to make this soup with chunked or shreaded corned beef.
