Adapted from a recipe I found in a recent issue of the Australian magazine ‘New Idea’. This recipe is strong on lemon flavouring so if strong citrus flavourings are not your scene, you may like to add ½ teaspoon nutmeg to the yoghurt topping instead of the lemon zest. I haven’t yet had the chance to make this recipe, but I didn’t want to risk misplacing it (little chance of that: I’ve adapted it to my liking already!), so I’m posting it here for safe-keeping. I’m absolutely intrigued – and excited - by the idea of a yoghurt topping: a healthier creamy topping! WOW! I’m always keen to double quantities of recipes like this one so as to freeze some dinners both for those inevitably busier evenings and for great take-to-work lunches. Freezing details have been included here. The canned tomatoes I use (Italian) have very little juice. If your canned tomatoes have a lot of juice, you may like to drain them. You can always add a bit of what’s been drained off, though I’m always keen to make some space for a bit of wine!
