Catherine Zeta-Jones has created the perfect sandwich - but husband Michael Douglas refuses to eat it because it's "gross". The Welsh actress reveals she has always been partial to smoked salmon sandwiches on brown bread with potato chips in the middle crushed down, and now she's added lemon juice, salt and pepper. She says, "I had them during each of my pregnancies and I actually had it two nights ago for dinner as well. It's one of those comfort foods I really love. "Michael hates it. He thinks it's gross... There's plenty of things I like to eat that make him really wants to throw up - like Marmite."
