While you might love using leftover roast beef for a sandwich with rocket and blue cheese or horseradish mayo, that's a harder sell for kids. They'll love these quesadillas though, which would be just as good for a midweek supper, served warm with some salsa and guacamole on the side, as they are cold for a lunchbox. The trick is to chop the beef as finely as possible to make it easier for kids to eat.
