I tried to do this but was a failure. I'd need to spend the ENTIRE DAY preparing all 30 days worth of meals, and I just can't do that, nor do I really want to. The book was enlightening and interesting. I bought it a while ago (when I was preg with ds1), but I really don't like casserole type meals every night. I like fresh stuff added in too. The book is worth borrowing from the library to see if you'd be into it, I think.
I do lots of food prep to save myself time though. When I cook rice, I cook a big pot full and freeze most of it for later meals. That saves some time. ALso, when I'm chopping veggies (sometimes I use the food processor for this) I'll do a whole bag of onions or peppers and freeze the rest for later meals. I do the triple batch cooking also, when I can. Most of the time that just gets eaten for the next day's lunch, but whatever.. that's one less pb&j sandwich I have to eat!
