Pulse to grind pecans and almonds just briefly in a food processor. Use a big enough bowl to allow you to add the remaining ingredients to it.
In a small pan, heat honey and butter until soft and blended well then add in the cocoa powder, vanilla and a pinch of salt.
Add honey/butter mixture to the nuts and process gently until blended together.
Add in the sunflower seeds and coconut and continue to pulse until blended. The pieces should be small, it will almost look too small but the pieces will group up when baked.
Line a baking sheet with parchment paper and spread the mixture out onto it.
Bake for 4-5 hours until crisp, stir mixture about halfway through but don't break down the pieces too small, you want them to clump together.
