Just my opinion... but I don't give them anything I wouldn't give my own kids. Ie: bad parts of produce gets cut off, rotten spots on potatoes, etc. I'm just talking really nasty parts not slight wilting or bug-bites.
Yesterday my girls got a heaping bowl of chopped fresh cabbage and another bowl of chopped apple and whole-wheat bread cubes. Yum! See - I didn't allow my children to eat white bread (except very, VERY seldom) so the girls don't get it either.
This morning they got a small bowl of chopped raw potato and a big bowl of bread cubes with a can of baked beans stirred in.
Since I am out of work (15 MONTHS now!) friends keep giving me food from their pantries. Some is good, some is OK, some I have to be desperate to eat. Sigh.
