Roughly chop the nuts you chose. Sliced almonds work really well, pistachios are the right size too, just rough chop larger nuts like walnuts and pecans.
In a large mixing bowl, add the coconut oil, vanilla extract, and honey, mix but it won't totally incorporate.
Next add all dry ingredients: chia seeds, cinnamon, brown sugar, pistachios, almonds, pecans, coconut, wheat germ, bran flake cereal, and rolled oats.
Mix all ingredients, place in single layer on a large unlined 10 x 15 sheet baking pan.
Bake 225 degrees for 1 hour, and stir every 20 minutes while baking.
Remove from oven, stir every 20 minutes until cool. This prevents the granola from forming clumps.
