Smoked haddock with spinach and mushrooms

As easy as it sounds - steam smoked haddock (in foil in oven, in a pan on low heat the hob with some water and a lid, steam in bamboo steamer - could add squirt of lemon juice...) sautee onion and sliced mushroom in olive oil.  When fish nearly done (15 minutes), wilt spinach with onions, mushrooms and a tablespoon of water.  Grind of black pepper.  Scoff. Simple, delicious.  (Can you tell that fish hating victim is off on their adventures?)
