How To Make Jamie Oliver 15 Minute Meal Mixed Fish Grill
- Prep and bake the fish: Roughly chop parsley and chilli, add to a roasting tray with cherry tomatoes. Crush in garlic, add 1 tbsp olive oil, lemon juice, salt, and pepper. Add fish fillets, prawns, and shellfish. Toss and roast at 240°C for 10 minutes or until shellfish open.
- Make the couscous: In a bowl, combine couscous with boiling water and season. Cover and set aside to absorb.
- Cook the fennel mix: In a large pan, heat sun-dried tomatoes, a splash of their oil, rosemary, and olives. Thinly slice fennel and add to the pan with salt and lemon juice. Cover and stir occasionally until just tender.
- Finish and serve: Fluff couscous, season fennel, and arrange on plates. Add roasted seafood tray on top. Serve with lemon wedges and dollops of yoghurt.

Recipe Tips
- What fish works best? Sea bass, bream, or any firm white fish. Mix for best texture.
- Can I skip the shellfish? Yes, just add more fillets or prawns instead.
- How to make it dairy-free: Skip the yoghurt or use a plant-based alternative.
- Do I need a processor? It speeds up fennel slicing but isn’t essential.
