Nice video; not sure if it will work with you with a big family but for me as a single guy it works great because not wasting food but some of the meals are small and I end up eating "both" meals.
I made meal today. There was left over. We trying not eat small portion. We give it one month to see this is for us. Specially my other son leaving to college . Then I have one child left she does not eat a lot. Will see these next meals.
