Food for LO throughout the day

Do any of you mamas have to pack food for LO to take to sitter or daycare? If so, what kind of things do you pack? Right now we are pretty spoiled because the sitter we have cooks all the time and so she feeds the kids every day. I do pack yogurt and applesauce and puffs for snacks but once she goes back to her regular sitter I will need to pack lunch items too. I'm a picky eater and so what I eat is crap for her and i want to make sure she eats well.
