About this recipe: Try these delicious easy flatbread melts topped with tuna, cheese and marinated onions.
Absolutely delicious. I make it in to a sandwich (use Warburtons sandwich thins) rather than having it on a flatbread, and it makes a gorgeous luxurious toastie for lunch. Love the flavour combination that comes out of the onions being marinated in the French dressing. One of my favourite recipes. - 10 Aug 2013
