In a small saucepan, combine the soy sauce, the ½ cup water, the brown sugar, honey, ginger and olive oil: cover with a lid and bring to a boil over medium heat.
Once boiling, remove lid and continue to boil, while stirring, for one more minute.

Once the sauce is boiling, add the slurry to the saucepan and stir in to combine.
Cook for another minute until the sauce starts to thicken and then remove from heat.
