Add the oil to a small saucepan over medium heat. Sauté the garlic and ginger until just fragrant, about a minute.
Add the coconut milk, maple syrup and tamari. Bring to a boil. Reduce to a simmer and cook until the sauce has thickened, about 5 minutes.
Pour over your noodle bowl and toppings immediately or let cool, store and reheat when ready to use. Enjoy!
