Buy some Ichiban noodles, lose the flavor packet and use instead a low sodium vegetable stock. Look in the "greenie isle" in your local supermarket and buy the stock from the EU. We can't get it here in Juneau, but I can find it in Anchorage, so might be a big city kinda thing.
The Ichiban packet is about the same size, costs twice as much and has a lot more calories. It also has less crap in it than raman. One packet with some dehydrated vegetables, stock and some dehydrated chicken is dinner for two. And that is just boil, pour and wait; no cooking.
Ichiban noodles taste better and, oddly enough, are probably better for you.
