I often have moments when I suddenly think "But WHY must 'X' food be that way".
Which is what happened here.
Granola & oat based snacks are often associated with sweetness, they contain 50% dried fruit & possibly additional syrups or honey too. Now they can be absolutely fine if had in moderation, but portion sizing with these things is never usually accurate I find.
So I thought why not put a spin on the whole thing & ditch the sweetness, instead looking to headily delicious cacao, a hint of fresh herby flavour & many layers of lovely fibrous nuts & seeds. Oh & some oats too.
