I bought the book & have to say I'm a bit disappointed in it. The recipes are good, but I was expecting more general tips (at beginning of book) on how to achieve these meals in just 30 minutes.
Yesterday I gave it a go & made one whole meal following his exact suggestions- it was the spinach & feta pie, plus cucumber & tomato salads, plus ice cream rolled in hazelnut, coffee & chocolate.
As tasty as the food was (and yes it was good enough), the timings were WAY off. The whole thing, just doing all the steps as he suggested, took me 50 minutes- and I'm an experienced cook, and have the equipment he says. It just took way longer than he says. But then on top of that, when I took the pie out of the oven, it was completely undone (given that it contains 5 eggs). So we put it back in oven & it took 25 more minutes to be ready.
So all in all: 1 hour and 15 minutes for the whole thing. Nothing like 30 minutes.
Either my oven is problematic (which it's certainly not, as I use it every day) or I didn't understand something in the recipe, or timings are just, very simply, too optimistic.
