I first made this for a piece I was writing for Vogue on the mood-enhancing properties of carbohydrates, as promoted by such books as - and how's this for a title? - Potatoes Not Prozac. The fact that shortly after filing the article I went on a low-carbohydrate diet should not worry us too much here, for I should say that no one has eaten this without being mad for it. It's a simple idea, and as simple to execute. What's more, there's a balance between the components - bland and sweet potatoes, almost-caramelised onion and garlic, more juicy sweetness with the peppers and then the uncompromising plain saltiness of the halloumi (which you should be able to get easily in a supermarket) - that seems to add to the eater's equilibrium in turn.
