I think my mom actually got this from my grandmother. I'm not sure if it was ever written down, I've always just made it from memory of how my mom makes it. The basic granola is just the primary ingredients but I usually add most if not all of the optional stuff.
Primary Ingredients:
4lbs (2 big tubs) of oatmeal
1 to 2 cups of chopped almonds
1 cup olive oil
1 cup honey
