Heat your oven to 220°C/Fan 200°C/Gas 7. Line a baking tray with greaseproof paper or foil. Pop the block of feta on the lined tray.
Grate the orange zest into a bowl and add half the cumin. Stir in 1 tsp oil and a few cracks of pepper. Pour the mix over the feta and turn the cheese over once or twice to cover all sides. Bake in the oven for 10 mins.
Trim and thinly slice the courgette. Halve the cucumber lengthways and thinly slice. Tumble the courgette and cucumber together in a mixing bowl.
Strip the mint leaves from their stalks. Roughly chop half the leaves and add it to the courgettes and cucumber along with the rocket.
Squeeze the juice from your orange into a small bowl. Add the rest of the cumin and a little sea salt and pepper. Stir in 2 tbsp oil till well combined.
Toss the salad with the dressing. Arrange on a large platter or individual plates.
Crumble the feta over the salad. Sprinkle over the remaining mint leaves. Thinly slice your chilli (fry in a little oil first, to crisp it up, if you like). Scatter over the top and serve.
