on my not-working days, I cook extra and then freeze it in portion sizes, so my working days is always leftovers, put in the fridge the night before so it doesn't take too long to zap in the micorowave. Things like lasagne, pasta & pasta bakes, beef stroganoff, curries, etc, all freeze really well.
As mentioned previously, the girls eat really well at day care, so I am not too worried if they don't eat too much at dinner in the evening.
We have a long drive home, so our routine is very much in the front door, dinner in the microwave, eat, bath, story, bed. then breathe.....
