In a large bowl combine the dries and mix well. In a seperate bowl whisk together the oil, honey, vanilla, cinnamon, and salt until blended, then pour over the dry ingredients. Mix thoroughly until everything is evenly coated.
Put the mixture in a 12"x18"x3" roasting pan. Bake 2 1/2 - 3 hours at 250 F, stirring every half hour, or until granola is evenly light brown in color and mostly dry.
Let cool completely. Serve with dried fruit and milk of your choice. Store in a sealed container in the refrigerator.
Note: A blender works very well to mix together the honey, oil, and spices.
