Preheat oven to 180 degrees fan forced, and place rack into middle of oven
Place pepitas and sunflower seeds onto a large baking tray and bake for 5 minutes, turn them over, and return to the oven for another 5 minutes, or until the seeds are lightly golden (it can take up to 14 minutes depending on your oven)
Put the seeds aside for 20 minutes to cool a little - set a timer
Turn oven off and open the door to let some of the heat out while you allow the seeds to cool
Once seeds have cooled for 20 minutes, preheat oven to 100 degrees fan forced
Line a large baking tray with baking paper and put aside (see notes on size of trays)
Place coconut, flaxseeds, puffed rice and seasoning into a large mixing bowl and combine
Place the egg whites into a separate clean bowl and whip until stiff peaks form
Place the egg white bowl onto a digital scale and add the honey to one side of the bowl (if you don't have a digital scale, place bowl on top of TM lid and weigh honey in)
With a soft spatula carefully fold the honey into the egg whites until you have a nice fluffy mix
Place toasted seeds into TM bowl and chop 4 seconds / speed 5, scrape and repeat 4 seconds / speed 5 (you don’t want to pulverise the seeds into a powder, just lightly crush them so there is still some texture)
Add the chopped seeds and egg white mix to the bowl with the remaining ingredients and lightly stir through to fully combine (it will look and feel like wet sand)
Place mixture onto lined baking tray spreading it out right up to the corners of the tray, using the back of a spoon to press into position and run across the top to level it
Place tray into oven and bake for 2 ½ hours until a deep golden colour
Remove tray from oven and allow to cool completely before breaking into shards and placing into a sealed container where it will keep for up to a month
