Start by chopping the zucchini and adding it to a skillet with 1 tbsp of warmed olive oil.
Sautee the zucchini over medium heat for 10 minutes, until softened.
Add water to a pot and set over medium to high heat. Once the water starts to boil, add pasta. Follow the instructions on the box for boil time (usually 9-11 minutes).
Add sausage crumbles to the zucchini, until warmed through.
Drain pasta.
While the zucchini and sausage mix are sauteeing, and the pasta is boiling. Prep the mozzarella cheese (cube, if not using the pearls), wash the cherry tomatoes, and drain and rinse the olives.
Put the drained pasta in a large bowl, then add the zucchini and sausage. Top with tomatoes, olives, cheese, salt, pepper, and olive oil.
Using tongs, stir to combine and serve.
