Darina Allen: Some ridiculously easy to make Japanese dishes

How about some Japanese food to really keep us in the Olympic vibe. Instead of ordering a pizza or a burger and a pint in a pub, why not impress the pals by whipping up a few super easy Japanese dishes from the host country for your socially-distanced viewing party or get-together.
Most of us would be hard-pressed to name more than two or three Japanese dishes… sushi immediately comes to mind but understandably many feel intimidated to even attempt to make sushi rolls. But scattered sushi, the most ancient form of sushi, is ridiculously easy to make and really delicious. How about ramen — silky noodles and many other good things in a bowl of deeply flavoured broth.
