Trim the fennel and cut into thick slices. Halve the marrow, scoop out the seeds and cut into rough chunks. Arrange the veg on a baking tray. Zest the lime and sprinkle over. Toss with 1 tbsp oil and a pinch of seasoning. Roast in the oven for 25 mins.
Set a heavy frying pan over a high heat. Rub the chops with salt and pepper and 1 tsp oil. Fry for 1-2 mins on each side.
Transfer the chops onto a baking tray. Slide into the oven for 12-15 mins, or till cooked through. Pop them on a plate. Loosely cover with foil to rest.
Halve the plums and scoop out the stones. Tip them into the frying pan and add 1 tsp turmeric and 1 tbsp honey. Cook for 1-2 mins over a medium heat till the plums start to caramelise. Add 4 tbsp water and simmer for 5 mins till it forms a sauce.
Drain and rinse the lentils, then tip into a pan. Squeeze the lime juice onto the lentils, and pour over any resting juices from the chops. Add 1 tbsp cold water and place on a medium heat. Heat the lentils, stirring carefully for 5 mins.
Spoon some of the lentils onto each plate and top with a pork chop. Drizzle over a generous amount of the sticky plum sauce and serve with the roasted veg.
