Ah, that's a point I forgot to bring up entirely. As a general rule, your side dishes should not taste like your entree. The entire point of having side dishes is to bring variety to a meal, and having a pineapple theme to a meal is completely counterproductive towards that end. When planning a meal, your goal should be to repeat flavors, colors and textures as little as possible.
It could be a great side dish to a different entree though, one with a more savory or salty flavor rather than sweet.
