I had very little experience with bagels at the time, because... my parents just never bought them. I don't know if it was just that they were trying to watch carbs or something, or if nobody knew what they were, or if we just weren't bagel people.
This Dad has found the solution to his kid's lunch issue. The kids demand sammitches with no crusts.... but then what? You can't just waste the crusts by throwing them out and letting the kids win, right?
