Onigiri is a triangle shaped sushi wrapped in Japanese seaweed. Onigiri is my favourite food to pack for work lunch, road trips and picnic. You can actually make onigiri a day in advance and just pack them in your bento lunch.
When you google for carrot cake probably you will get two versions of it. One is the sweet carrot cake with cream cheese frosting and the other one is the savory version which is stir fried with egg omelette.
