Preheat your oven on the highest setting. Cut eggplant in half and place on a roasting sheet cut side up. Slash the flesh by cutting through about 2cm (1in) deep in a criss cross pattern. Drizzle the cut side with oil and sprinkle over a pinch of salt. Roast eggplant for 20-25 minutes or until soft and well browned.
While the eggplant is cooking, brown pork / beef in a frying pan with a little oil. Keep a few coriander leaves aside to serve and finely chop the remaining stems and leaves.
When the meat is browned, add the chilli and herbs and cook, stirring for 2 minutes or until herbs have cooked down. Remove from the heat. Add lime juice. Taste and season with salt and more lime if needed.
When the eggplant is cooked divide between two serving plates. Spoon over the meat mixture. Top with crumbled feta and reserved coriander (cilantro) leaves.
