The average family currently spends $300 a week on groceries. Fiona Lippey and Jackie Gower show you how you can slash hundreds of dollars off your grocery bill with their week-long $21 Challenge. Packed with recipes, menu plans and tips, The $21 Challenge provides you with all the strategies you need to stop rushing off to the shops every five minutes and start making use of the food you already have in your fridge, freezer and pantry. It will help you to: create a menu plan based around items hiding in your pantry; reduce waste by using up forgotten items lurking in your fridge; find a way to turn even the most random ingredients into a meal; balance a week's worth of meals for variety and nutrition; substitute ingredients when a key component is missing; make the most of leftovers.
