Season the fennel quarters with salt and olive oil. If you have access to a BBQ, char the fennel on the BBQ for a few minutes on each side. Or you can use a frying pan instead.
Roast the fennel in the oven with olive oil for 20 minutes or until al dente. Set aside.
Warm a frying pan over a medium to high heat. Once the pan is warm, add 20ml olive oil, then add the prawns.
Cook evenly on each side, turning halfway through. This should take around 3-5 minutes in total, depending on the size of the prawns
Once the prawns have turned pink almost all over, add the garlic and toss continuously until the prawn are fully cooked and the garlic is lightly golden
Add a nice pinch of salt, the lemon juice and parsley
Remove from heat and serve immediately, on a platter together with the roasted fennel quarters
