I took Fluffy's advice and tried out the Hairy Dieter's cookbook. I started on the first recipe. The first section of the book is just breakfasts, so I had breakfast for tea in effect. Recipe 1: Toasted Crumpets and Warm Spiced Berries with Yoghurt and Honey.
The instructions were easy to follow, although this WAS an easy recipe. Whether I'd manage to put it all together on a Thursday morning before work is another challenge, but it was fine trying again this morning. Reasonably enjoyable. A little too sweet, mind. It was supposed to serve two, but I mullered the lot. So much for dieting.
Time to learn a main evening meal, I think.
