Jamie Oliver has long promoted the idea of healthy home cooking, done quickly. His cookbook 30-Minute Meals, released in 2010, proved that making nutritious dinners at home can be easy, fast and affordable. A couple of years later, he dialled up the pressure with 15-Minute Meals. Both books aimed to give people a repertoire of quick dishes that could feed the family well without having to fall back on pricey or unhealthy takeaway foods.
