Step 1

Preheat oven to 200°C. Soak 4 wooden skewers in boiling water for 10 minutes. Combine the garlic, 2 tablespoons oil, half the lemon zest and plenty of salt and pepper in a bowl. Add the tuna, toss to combine, then cover and place in the fridge to marinate for 15 minutes.

Step 2

Meanwhile, place tomatoes on a baking tray and drizzle with 1 tablespoon oil. Bake for 8-10 minutes until starting to soften.

Step 3

Preheat a chargrill pan or barbecue to high. Thread marinated tuna onto soaked skewers and cook for 1-2 minutes on each side for rare, or until cooked to your liking.

Step 4

Whisk sugar, lemon juice and remaining zest and oil together, then toss with the zucchini, chilli, mint and pine nuts. Serve with the tuna skewers and tomatoes.
