  1. Melt the butter in a large, deep frying pan. Add the garlic and cook for 1 min, then pour in the stock and simmer until reduced by half.
  2. Add the frozen spinach and cook for 5 mins until piping hot. Stir in the cream, Dijon mustard and season well. Add the salmon to the pan and cook in the sauce for 5-10 mins until the sauce is slightly reduced and the salmon is cooked through.
