Yadda, I really can't add anything here as my favorite pizza topping is Italian sausage, often with some pepperoni added. I'm old school, I know. But of the few people -- in my circle of friends at least -- who were not sausage lovers, I've learned that their dislike came from trying a type of low grade sausage (example, some "pellets" passed off as sausage) or something similar that most reasonable people wouldn't like. Maybe, just maybe, your wife got her dislike from trying something that was not of a decent quality sausage. Maybe that's not the case, but you never know. In Chicago, sausage is the Number One requested ingredient for Chicago Style Deep Dish pizza, followed by pepperoni, green peppers and mushrooms. But as you've indicated, there are many others to try out.
