Nature Valley Popcorn Bars

Unless you live under a rock, I'm sure you're well aware that popcorn is seriously on trend. It's been incorporated into ice-creams and chocolate bars, and now it has a bar of it's own: Nature Valley is launching a range of Popcorn Bars available in two flavours: Cranberry & Yoghurt and Peanut & Sunflower Seed . Each popcorn bar has less than 100 calories and come in multipacks containing five individually wrapped bars (Sainsbury's, £2.80), with Peanut & Sunflower Seed also launching in 20g single bars.
