These series of BBC cookbooks contain normally good, reliable recipes that have previously been published in the BBC Good Food Magazine (Olive Magazine for some of the other books) and often on the BBC Good Food website, too. What makes them extremely practical is that you can easily put them in your bag (even your handbag!) on a busy day, and then just choose a recipe when you're actually in the supermarket, or perhaps during lunch break, or whenever.
I have found this specific book to be the less useful one of the four books of the series I own (Olive 101 Quick Fix Dishes, 101 One-pot Dishes, 101 Store-cupboard Suppers and this one), although I believe that I eat quite healthy - possibly for the simple reason that I'll just grab the others quicker.
