I've been using a hamburger box lately. It has a nice capacity but it leaks, so I often discover that my bag is smeared with juices from salads... This is the main disadvantaged of this box. It's shape is round so it turn over easily in a bag.
Fried fish, grapes, cabbage salads and boiled egg with cheese.
Soba noodles wits sesame, boiled egg, tomatoes and cucumber. The little orange guy is a mayo container. i made it from "Kinder surprise" :) It does the job perfectly :)
Deep fried dumplings in teriyaki sauce, rice balls, zucchini and egg.
Lavash rolls with soy meat and veggies. Potatoes pancakes wit soy meat and carrot salads with mayo. And boiled egg of course :)
