Last time I shared a bento post was August 2014… Almost 10 months ago. I didn’t mean to drop my bento series at all, but we’ve started to focus more on making YouTube videos and our priority got shifted a little bit.

I know some of you have mentioned that you really enjoy my bento series so I’ll definitely do my best to continue next school year. I just have to be more disciplined!

Have you been to one of the popular Japanese diners called Ootoya (大戸屋) in Japan? Outside of Japan, there are 3 locations in NYC, and the restaurant chain is also popular in Taiwan, Hong Kong, Singapore, Thailand, and Indonesia.

My favorite meal there is this popular sweet and sour chicken & vegetable dish called Tori Kurozu An (鶏と野菜の黒酢あん). Their sweet and sour sauce with black vinegar is one of their specialties and super delicious! This dish requires deep frying so I don’t make it often. However, when I make it, it’s a wonderful treat and our family really enjoy it!

On previous day, dinner was: Ootoya’s Sweet and Sour Chicken.

Assemble Sweet and Sour Chicken Bento

With the leftover, I packed the sweet & sour chicken into bento lunches for the next day. Here are what goes into the bento box:

How to Heat Up Bento

Now if you’re wondering about how to heat up bento… you might be surprised to learn that most Japanese are used to eating room temperature bento. Microwaves are not available in school and we typically eat bento at room temperature. Therefore, we usually pack food that tastes good even without heating up. One trick is to season the food slightly more. It’s very common to see deep fried food, food that covered with sauce, and salad that still taste pretty good at room temperature in a bento box.

As you may not be used to eating bento at room temperature, I understand this might not work for everyone. Please use Thermos food jars to keep hot foods hot (by lunch time, it’s usually “warm”) and cold foods cold for hours. I do use the food jars as well for certain dishes. If your school or work has a microwave, use a microwave-safe glass container to pack your lunch. It’s wise to separate hot foods and cold foods so you don’t have to take cold foods out in order to microwave hot foods.

Hi,

Had been copying your recipes to my pc thank you so much! Son is 2 year old+, attending daycare, had been really worry about his meal that parents have to prepare everyday, i personally like Japanese food although can’t take raw food but the principles are impressive and love the balance of food groups.

Again thank you and hope to see your continuous success.

Best regards.

Hi Nami! You really cook in the feature! Lol literally! I thought you mean August 2014!
I love your new entry is such a great idea for when you have few friends coming over for dinner! That would be lovely! Thanks again!
u rock!

May I come and go to school with your two next Fall to have a bento box like that for lunch!! Love every bit of it: a feast for the eyes and then your ‘tum’ . . . please post some more variances for us even if they do make us feel peagreen 😉 !! I eat a lot at room temperature: Middle Eastern cuisine is another one which lends itself readily to ‘not hot, not cold’ treatment!!

Such a beautiful presentation – that much more mouthwatering! A varied selection of yummy savories, this is why I enjoy making bento so much!
