You know I rattle on and on about making extra for leftovers - and I even do it with burgers! Yeah, burgers make a fine leftover for school lunches.
We had cheeseburgers for dinner, so I made extra. It's back to what I've said before about kids eating cold food - my kids never eat their dinner while it's still hot, so it's really no different for them to eat their lunch at room temperature. These are plain cheeseburgers, which is just how my kids like them. On the side they have sugar snap pleas, grapes, and potato chips. It's a nice little change in variety for lunch.
The one who doesn't like meat got a toasted cheese sandwich.
