Melt the oil in a small to medium skillet over low heat and add the oats, coconut, and cashews. Stir constantly for 3 to 4 minutes until toasted and fragrant. Stir the syrup, sugar, water, vanilla, salt together in a small glass and pour over granola. Sprinkle with cinnamon and ginger and continue stirring until the sugars are starting to candy and the granola is very dry, about 5 minutes (watch carefully at this point not to let the sugar burn.) As soon as it's crisped and brown, remove pan from heat and allow the granola to cool in the pan for at least 30 mintutes.
