Wash or scrub the potatoes, halving any larger ones, and put them into a large saucepan, with the herbs and the halved lemon. Cover with water and bring to the boil. Boil until just cooked, then drain and set aside.
Season the pork loin steaks on both sides with salt and pepper, and a little olive oil, then griddle on a high heat until just cooked through. Cooking pork steaks in a frying pan or griddle should take 4-5 minutes on each side, depending on thickness.
Boil the broad beans for 2 minutes, then drain, and remove and discard the tough skins
Steam the green beans lightly for 2-3 minutes
Sauteé the spinach in a splash of olive oil with the chopped chilli and garlic, until wilted
Just before you're ready to serve, heat the butter in a large frying pan until foaming. Add the potatoes and beans, and toss to coat for a minute
Put a layer of spinach in the bottom of each dish, spoon over the potatoes and beans mixture, and top with the pork. Drizzle over a little good quality olive oil, and serve with a salsa of your choice. We used Jamie Oliver's Salsa Verde (see link below)
