I won't give this a proper rating until I've at least used it for a fair trial period. But I bought it because I'm absolutely terrible at cooking and know how to cook very, very few things (and I'm in my mid-30's). I like the fact that these meals claim to be doable in less than 30 minutes or so, which makes it much more approachable for me to attempt them.
I'm also a very visual learner, so I appreciate the fact that this book not only has nice colour photographs of the actual dishes described, but I also really like the hand-drawn pictures of ingredients, or in-progress photos of items being placed in a frying pan, etc., etc. All of those details really help me grasp the entire process and all work toward making it very approachable for me.
My above impressions alone will probably lead to me giving a 5-star rating - but I really should try out some of the recipes first before that!
