We've done the freezer thing in the past. It has worked ok if things are labeled and prioritized. That's the problem! I would rather throw it away out of the fridge in a week or two versus it getting lost in the freezer for a year or two and throwing it out then. I process a lot of meat myself and really hate a cluttered freezer(s) that eats up useful space.
I do eat a lot of things for lunch from the leftovers but my work schedule is somewhat unpredictable so I may go a week eating out(unavoidable
)and the food is still there. On the other hand, at times I may be working close to home or at home which makes things easier. I don't have a regular "9 to 5" schedule that would make using leftovers a bit easier.
