Preheat oven to 180C/160C fan forced. Line 2 baking trays with foil.
Cut the cauliflower into four 1.5cm-thick slices, leaving base intact. Cook steaks in extra virgin olive oil in a non-stick frying pan over medium-high heat for 2-3 minutes each side or until golden. Transfer to the foil-lined baking tray.
Whisk the olive oil with the turmeric in a bowl until combined. Brush over steaks.
Roast cauliflower in the oven for 12-15 minutes or until tender and crisp.
Scatter with fried curry leaves and thinly sliced red chilli, to serve.
Recipe serves 4, so you can pop the left overs in the fridge and eat the next day.
