ASANDWICH AT YOUR DESK is all very well, but as the days get colder, those cravings for a hot lunch start to kick in. If this usually means a ready meal you can pop in the office microwave, it’s worth looking at the ever expanding range of healthy grains, rice and lentils appearing on the shelves. They can be ready in even less time (on average, a pack heats in 1.5 minutes) and prove that microwave options don’t need to be high in calories, fat, salt and a long list of unwanted ingredients.
