Mix all the coleslaw ingredients together, reserving a few slices of radish for the garnish.
In a jar with a lid, shake the dressing ingredients together. Taste & adjust the seasoning to how you like it.
Mix the dressing through the slaw. You'll probably have too much dressing, so screw the lid back on the jar & pop it in the fridge for another day.
Pretty up the top of the slaw with the reserved radishes.
Notes
This is super tasty with the addition of some lightly toasted pumpkin seeds. Sub or add in other crunchy slaw ingredients. Fennel, Kohlrabi, grated celeriac or finely chopped red onion would all be fabulous here too.
