I came across Nice & Natural granola bars at Costco a couple weeks ago. They are certified Gluten Free and carry the GF symbol.
The box from Costco has 3 flavours: Apples, figs & Walnuts; Pistachios & Mixed Berries; and Cranberries and Cashews. They are dairy free, have no refined sugars, and are low in sodium. Each bar is about 150 calories, so they make a great snack.
I like all the flavours, but my favourite is the Cranberry, followed by Pistachio. They have an excellent crunch and chewy factor, and they slightly softer than a traditional Quaker chewy bar.
It was $14.49 for a box of 24 - which is a really great deal for GF bars!
I can't seem to find a website link, but I've posted a picture of the box :)
