The fresh, deliciously mild courgette becomes "sexy", when mingled with the heat of the chilli and the black pepper and the fragrance of the tuna and the garlic. The final sprinkling of cheese really is a "Gran Finale" complete with red chilli fireworks!
Stir and watch for a couple of minutes, until the garlic turns a lovely golden colour. Drain the tuna,pour into the oil and chilli mixture together with the grated courgettes. Keep the heat quite high, as this helps the flavours mingle and develop.
