Step 1

Heat 1 tbsp olive oil in a deep frying pan and gently cook the onion, carrot, celery, rosemary and some seasoning for 15 minutes until really soft.

Step 2

Meanwhile, heat a non-stick frying pan until medium-hot. Drizzle the pork portions with a little oil and season all over. Cook for 5 minutes on each side until really golden. Put onto a plate and cover tightly with foil to rest for 10 minutes, then slice.

Step 3

Add the lentils, lettuce, lemon juice and balsamic to the onion mix, stir through and cook for 2-3 minutes until the lettuce has just wilted. Season and stir through the parsley and any resting juices from the pork, spoon onto plates and top with the pork slices.
