Lamb steaks with caper and tomato sauce

Method

• Step 1
  Heat 1 tablespoon oil in a frypan over low heat. Add onion, garlic and rosemary and gently cook, stirring, for 5 minutes until softened. Add beans and a splash of water, season, then cover and simmer over very low heat for 5 minutes. Add another 2 tablespoons oil, then mash the beans with a fork until smooth. Cover and keep warm.
• Step 2
  Meanwhile, heat remaining oil in a pan over medium-high heat. Season lamb, then cook for 3-4 minutes each side for medium-rare, or to your liking. Remove to a plate, cover with foil and set aside.
• Step 3
  Add tomatoes, capers and a little salt and pepper to the lamb frypan and cook, stirring, over low heat for 3-4 minutes until tomatoes have softened. Stir in any resting juices from the lamb. Slice the lamb, then serve on mash with the tomato sauce, garnished with the basil.
