Grilled Mediterranean Tuna - cooking recipe

Ingredients

1 1/4 lbs tuna steaks, cut into 1 inch strips
6 tbsp olive oil
1 None large lemon, finely grated rind and juice
1 tbsp white wine vinegar
2-3 tsp fresh thyme
1 clove garlic, peeled and crushed
1 head fennel, cut into thin wedges
1 None red onion, sliced
4 None tomatoes, thickly sliced
None None Arugula, to serve

Preparation

Place the tuna in a shallow non-metallic dish. Place the olive oil, lemon rind and juice, white wine vinegar, thyme and garlic in a small bowl. Season to taste. Whisk together with a fork to make a dressing. Pour one-third over the tuna. Leave to marinate for 30 mins.
Heat a grill pan until smoking hot (no need to grease). Add the fennel and onion. Cook for 5-6 mins, turning once, until tender and charred. Transfer to a plate. Cover and keep warm.
Place the tuna on the hot grill pan. Cook for 2 mins on each side, or according to taste, until just cooked through. Add the tomatoes to the pan for the last 2 mins of cooking. Divide the tuna, tomatoes, fennel and onion between 4 plates. Spoon over the reserved dressing. Serve immediately with arugula.
