Place all ingredients for the dressing in a saucepan and boil for 2 minutes, then cool.
Peel and cut the fennel bulb and Chioggia beet into paper thin slices. Place the vegetables in iced water for 20 minutes. Drain and pat dry.
Cut the courgette into sticks.
Combine all ingredients and toss in the dressing.
Notes
Placing thinly sliced vegetables in iced water will make them crispy. This is applicable for most of the root and tuber vegetables such as fennel, radish, carrot, daikon and beetroot.
