Line a 25cm square tin with baking parchment.
Place the puffed rice cereal, oats, seeds, flaked almonds and dried fruit in a large bowl and mix to combine.
Place the peanut butter, honey, brown rice or golden syrup and salt in a pan. Heat gently while stirring until it is melted and smooth and just starting to bubble.
Pour the mixture into the oat mix and stir well to combine, there should be no dry patches. This is a little tricky and I found the easiest way to mix it well was to get your hands in there and mix it by hand.
Tip the mix into the prepared tin and spread level. Use your hands or the base of a glass to really pack it down firmly, you want it to be really packed down or your bars will crumble.
Place the tin in the fridge for at least a couple of hours then lift the slab out using the baking parchment and use a very sharp serrated knife to cut it into 16 bars. Wrap each bar in clingfilm and store in the fridge.
