I"m more with the wing-it ladies. As often as possible it's our night before's leftovers or whatever else I have in the fridge. I try to tell the parents a day ahead what we'll be eating tomorrow. If I'm having a SUPER organized week, they may even know 2 days ahead by their daily journals. On some days at 11:45 I throw on some rice and stir-fry a bunch of veggies....or anything else that easy that is healthy!
This is year is tougher now planning dinner, daycare lunch, hubbie's lunch and my 2 kids school lunches. Sometimes my dinner just doesn't stretch that far.
