Prepare the braai and coals. Crush the garlic and chillies lightly in a pestle and mortar. Add the feta, parsley and olive oil and mix gently. Season well. Place the snoek fillets skin-side down onto the braai grid. Baste with the butter and drizzle over half the chilli-and-garlic oil. Braai the fish for 10-15 minutes until the fish flakes. Serve with steamed courgettes and rice. Drizzle with the remaining chilli-and-garlic oil. Serve with a chilled Grolsch!
