Even though it's Japanese, of course instant noodles are not healthy but they would make you happy when you are too busy and starving to cook and there is nothing to cook. Here is the sample of normal priced 300yen(about 2.5USD/1.5GBP. The cheapests are 1USD/0.6GBP) instant bowl-ramen(Chinese noodles developed as Japanese style food). It has dried noodles and theree packets of seasoning powder with dried vegetable, "cha-shu"(cooked pork in soy-sause) with bamboo-shoot and soup paste.
The soup paste contains a lot of fat to make the taste rich. I don't recommend emptying all the fat from the packet. You'll still get rich enough soup. I often add dried seaweed which become edible just putting in the hot soup. The taste of this ramen soup is fatty soy sause.
