Crunchy granola bars with hazelnut pieces: baked rolled oats with hazelnuts pieces. Nature Valley Crunchy & More? As the name suggests we've added something a little special to our satisfying and delicious crunchy granola bars that we've been lovingly baking to perfection since 1975. Of course there's still wholegrain oats, but now we've added crunchy hazelnut pieces for more flavour and an even crunchier texture. Enjoy them like we do as a breath of fresh air - when out and about - or at home relaxing.
