Most days, we don't have time to make an elaborate side dish, and something simple is all we crave. This easy, quick-sautéed zucchini is the perfect side dish for those nights. It's full of flavor, and the zucchini slightly caramelizes as it cooks in the cast-iron pan. It's our favorite way to use up zucchini (beside chocolate zucchini bread, of course) and you can catch us eating it as our lunch almost weekly.
