I think it was on an episode of MasterChef Junior that I heard the quote "what grows together, goes together" which makes so much sense. Zucchini, tomatoes and basil are just made for each other, you can serve as a side dish, as suggested, or even as a main dish topped with some grilled shrimp or chicken.
I've been using the thicker blade on my Paderno Spiral Vegetable Slicer to make my zoodles (zucchini noodles). I like the larger noodle because it has more of bite and I'm careful not to overcook them so they don't get soggy. Under two minutes is all they need, then I quickly remove them from the hot skillet or they will keep cooking.
