Using this framework, you can make granola at home using ingredients you probably already have in your pantry. It's a wholesome, delicious snack that's loaded with protein and fiber, and you can make it your own by adding different flavorings and fruit.
Put the oven rack in the middle position and preheat the oven to 340 degrees F (170 C). Line a baking sheet with parchment paper.
Add the rolled oats, chia seeds, coconut, cashews, okara powder, and coconut oil to a bowl and mix everything together until the oil is evenly distributed.
Add the rice syrup and continue mixing until the syrup is evenly distributed and the mixture clumps together when squeezed. If it doesn't clump, you can add more syrup until it does.
Spread the granola mixture evenly onto your prepared baking sheet.
Bake the granola for 30-40 minutes. If your granola isn't browning evenly, turn it around halfway through.
When the granola is golden brown, remove it from the oven and let it cool completely on a wire rack.
Break the cooled granola into clusters and then toss in the chopped mangos.
Store your homemade granola in a sealed container.
