I'm a special ed teacher too, so I know how short lunches are. If we're lucky we get 20 minutes...usually not that lucky. I have a refrigerator and microwave at school too. I always keep 'go to' things in my closet and frig like tuna kits, protein drinks, protein bars, greek yogurt, healthy snacks, etc. I try to cook extras for supper to take. I looked into those containers. I'm a real sucker for 'gadgets' that really aren't necessary...or at least not for me. I already have a ton of containers. The ones I use the most are the cheapest that wal-mart has that are supposed to be disposable. That's been my experience anyway. This is my last week before school starts, so I better get stocked up! Have a great school year!
