Cook the pasta until al dente then drain, reserving some of the pasta cooking water to make the sauce.
Heat the oil in a skillet over medium high heat and then sauté the zucchini for 1-2 minutes until just barely softened. Add the pasta, cheese, and pepper to taste to the skillet along with some pasta cooking water and stir together to make a light sauce.
Season with salt to taste and serve immediately.
