Sauté zucchini. While pasta is cooking, heat 2 tablespoons olive oil in a large frying pan (one that can hold the zucchini in a single layer is best) over medium-high heat. Once visibly shimmering, add zucchini and stir to coat in the oil then spread out to an even layer. Let cook, undisturbed until brown on one side, then stir and continue cooking and occasionally stirring until zucchini is tender, but still retains a little bite, about 5 minutes total. Season with the teaspoon salt and 1/2 teaspoon pepper Remove from heat. It will seem salty but will be good once you mix it with the pasta.
