Ham, pineapple, onions, green peppers, and jalapenos, no sauce. One of my favorite pizzas.
There’s enough goodness that you really don’t need pizza sauce on it, or at least I’ve never come across a sauce that works with pineapple. But the flavors and textures work well together.
Plenty have been fighting for it, but there’s an uphill battle against “but that’s socialism and socialism is evil!” and those that personally benefit financially who stand in the way.
