Preheat the grill to high. Finely chop the spring onions, keeping the white and green parts separate. Melt one tablespoon of the butter in a large saucepan with a lid. Add the whites of the spring onions and cook for 1 minute.
Add the seafood and mussels, then increase the heat and fry for 1 minute. Add the wine, remaining spring onions and season. Cover and cook for a minute or two until the mussels are just open. Add the cream (if using) with the tomatoes and remaining butter. Toast the soda farls and then place each one in the centre of a warmed serving plate. Spoon the butter and spring onions over the seafood and sprinkle over the chives to serve.
