In a small mixing bowl, add the garlic and ginger and combine with the rice vinegar, sweetener, Sriracha, soy sauce, fish sauce and lemon juice.
Add the grated radish, grated carrot, cucumber and cabbage and stir to coat.
It's ready to serve straight away or you can store it in a jar or air-tight container and keep in the fridge for up to 2 weeks. This will make the flavour more intense.
