Steamed salmon with hot and sour green beans

Method

1 In a large pan, add oil then onion and a pinch of sea salt. Cook till onion starts to caramelise. Remove, then mix onions in a small bowl with soy sauce and lime juice. Taste, and put to one side.   

2 Fill a large pan a quarter of the way up with water, add lemon halves and bring to boil, then reduce to a simmer. Lay salmon fillets in a metal colander. Sit this over pan. Put a lid on colander and cook till cooked through (6-8 mins). Remove and put to one side.         

3 Add beans to another pan of boiling, salted water and cook till they still have a bite to them. Drain, then rinse under cold water. Toss with onion dressing. Carefully lift salmon from colander and remove skin. Sprinkle over chilli, if using, and serve with beans and lime wedges.
