Oh - finally a question I can answer.
I LOVE making lunches. Yes, you read that right. I lived in Japan when my kids were little and I used to buy these neat magazines on Bento - Japanese packed lunches - and really enjoyed making them; however, 30 minutes is a quick Bento! I have adapted. I have also overpurchased crazy luchkit accessories. My two boys asked me to stop cutting out sandwiches in heart or bird shapes - apparently that is not cool in middle school. The banana keeper was also not a hit:

1. I make pizza dough on Sunday evening. I actually use the cinnamon bun recipe for the dough and double it:
http://allrecipes.com/recipe/ooey-gooey-cinnamon-buns/ 2. I use the cinnamon bun dough to make... yes, cinnamon buns.. which I use for breakfast or snacks for lunches. The rest I use to make mini-pizzas or calzones for the lunch boxes. I also make pizza and cheese buns.
3. I have a rice cooker. I make brown rice and make rice balls (onigiri) for lunches in the mornings:

5. My kids like soup. I make a quick soup with Better than Bouillion or Miso in thermoses and pack cooked noodles separately for them to add so the noodles don't get mushy.
6. I mix up a largish batch of pumpkin pie filling using pumpkins or sweet potatoes. I cook individual pumpkin tarts in the mornings as a side. I freeze extra filling so it is always fast. I also make fruit tarts and pecan tarts. Extremely easy and fast. Banana bread is always popular.
7. I have a garden. The kids get raw vegetables as a side. Right now it is peas, purple beans and tomatoes. When the garden runs out they get cucumbers, peppers and baby carrots from the store. They pick them from the garden in the morning.
8. I pack fruit each day in their lunches. Whatever is in season. I get a lot of it from the garden (strawberries, apples, plums, blackberries and raspberries). Otherwise I buy it - mandarin oranges are really popular.
9. I buy big tubs of Greek yoghurt and put it in smaller containers.
10. I have found this style container useful for ensuring variety and freshness:

http://www.thegalleygourmet.net/2012/04/homemade-chicken-nuggets.html or
http://allrecipes.com/recipe/the-best-meatballs/ which can be easily baked from frozen and added to the rice or pasta dishes for lunches.
12. Boiled soybeans (edamame) are a great side for lunches and kids usually like them.
13. Kids like popcorn. Package some up from the evening before and they will likely eat it with lunch.
14. Homemade bread is popular. I make this frequently and use it to make sandwiches:

15. I use tortillas for fast wraps that are grilled first and usually pizza-like in content (the kids like this).
16. Hard-boiled eggs. I can't resist doing this with them:

My husband always gets leftovers. This week I made chicken with rice, chili and coconut/sweet potato/kale soup. I package and freeze/refrigerate the containers so I mostly just have to pull stuff out and add fruit and a cinnamon bun or tart. His lunches are the fastest.
