While the quinoa is cooling place the nuts into a handheld food processor (or ordinary food processor) and blitz until it turns into a butter. You will have to stop and scrape down the sides several times before the nuts become a butter
Add the banana and blitz until smooth
Add the sunflower seeds, sesame seeds, coconut oil and salt and blitz again until roughly combined
Finally stir through (or quickly blitz) the popped quinoa
Tip the mixture into a lined tin...choose one that will give you the sized bars you require. I used on that was approx.25cm x 10cm, and press firmly into the edges smoothing off the top
Scatter the cacao nibs, if using, on the top and press gently into the mixture
Place in the freezer to set before turning out and cutting into bars
