Preheat the oven to 300° F and line a large rimmed baking sheet with parchment paper (or spray with nonstick cooking spray)
Place all the dry ingredients in a large bowl and stir to combine.
Place the wet ingredients except for the egg whites, in a small saucepan and warm over medium heat until the honey thins out and everything is combined well. Pour the honey mixture over the dry ingredients then whisk the egg white and pour it over the dry ingredients. Stir to moisten everything.
Dump the granola into the rimmed baking sheet and spread it out to the edges. It will come up to the edges of the pan, keeping the mixture piled up thick like this will keep the granola soft and chewy.
Place in the oven and bake for 55 to 65 minutes, stirring every 20 minutes. The mixture will be toasty and golden.
Remove from the oven and let it sit without stirring for 10 minutes (this will help it form larger clumps) then give it a stir and let it sit until completely cool.
Store in an airtight container for up to 2 weeks.
Notes
I used soft dried apples to help contribute to a chewy texture but crisp dried apples would work just fine in this recipe as well.
You will need a half sheet pan (18x13 inches) to fit the whole batch on one pan. If you use smaller pans then spread the batch out on two separate pans and rotate the pans half way through the baking process.
