Thought of this after my trip this year (of course)...

I'm going to try it at home first, but my 700ml cup looks like it's about the same size as the cup the instant ramen/ramien noodles come in. I'm going to put some boiling water in my cup at home and toss one of those in. If it works (big enough to hold the soup and noodles), next year, I'm going to buy the noodles, take them out of the cup and put them in plastic bags, then just toss them in a cup of boiling water.

When most of the noodles are gone, I toss some tuna in. Lots of protein and carbs and if you get the Korean hot stuff, lots of red pepper and garlic. Warms the cockles of your heart, among other things, on a cold day.
