These Breakaway bars always used to be in my nan's cupboard when we went round to visit as kids, I was never overly fussed on them to be honest, but on discovering how cheap they are and that they're only 99 calories per bar, they have now found their way into our cupboard as a regular occurrence.

The Breakaway bars will be recognised by most people as they have been round for years. They are individually wrapped in yellow, making them ideal for a lunchbox filler or afternoon treat. They're not the biggest bars in the world, they're only about three inches long, but they do provide a chocolate hit when you need it, and they're quite thick so they feel substantial. I personally would describe them as more of a biscuit than chocolate bar, but they are covered in chocolate so you get the best of both worlds.

The bars themselves are made from wholemeal digestives and covered in a thick layer of chocolate. They are quite chunky and have a bit of bite to them. You can taste the biscuit through the chocolate so there is a good ratio here of biscuit to chocolate. The taste gives you a pleasant hit of chocolate, but I notice they don't leave the nicest aftertaste in your mouth.

Nutritionally, you don't have to feel guilty about treating yourself to one of these. They are made from 100% wholemeal and oat flour, contain no hydrogenated fat, are free from artificial colours, flavours, sweeteners and preservatives. Each biscuit only has 99 calories, 8g sugar, 5g fat, 3g saturates and a trace of salt.

These bars are only sold in multipacks, making them good for families and people needing lunchbox fillers. They cost £1.55 for a pack of 9 in Tesco, but are currently on a buy-one-get-one-free offer. They are available in larger multipacks, with a pack of 18 currently costing £2 in Tesco (although obviously you'd be better getting the two packs of 9 whilst the offer is on).
