For the granola:
Preheat the oven to 325 degrees.
In a very large bowl, combine the oats, almonds, pecans, whole wheat flour, cinnamon, salt, and sugar if using. Stir to combine.
Whisk the melted coconut oil, maple syrup and the honey together. Pour over the oats mixture and stir until the mixture is well combined and is completely coated. Pour into a large baking sheet in a single layer. It will be a thick layer, which is okay, you want it to create large clusters.
Bake for 20 minutes, stir and bake for another 10 minutes. Stiry again and bake for a final 5 minutes and remove from the oven.
Do not stir right away. The granola will will become more clumpy as it dries.
When granola is completely cooled, layer 1/4 cup of blueberries in the bottom of a glass. Add 1/4 cup of yogurt on top, then add 1/4 cup granola. Add 1/4 cup sliced strawberries and blueberries, another 1/4 cup of yogurt and another 1/4 cup of granola on top. Garnish with more blueberries and strawberries and serve immediately.
