Preheat the oven to 180C.
Cut the cabbage into 2cm thick slices . Rub them with the oil on both sides and place them on a baking tray. Scatter the thyme leaves on top, then season with salt and pepper.
Bake in the oven for 10 minutes, then carefully turn the steaks over and cook for another 10-15 mins or until the edges are golden. Scatter the nuts around the cabbage for the last 5 minutes of baking.
Meanwhile, mix the spread or butter with the chopped herbs and lemon zest. Add a pinch of salt and ground pepper.
Crumble the herby butter on top of the steaks and scatter the pomegranate seeds on top.
Serve warm.
