Directions

1. In a saucepan, soften the onion in the oil. Turn heat to high, add the ground beef and cook, breaking up the meat with the back of a wooden spoon, until all the cooking juices have evaporated.
2. Add the zucchini and cook for a few minutes. Add the tomatoes, salt and pepper and cook 15 minutes, uncovered, over medium heat.
3. In a large pot, cook the pasta al dente, following package directions. Drain without rinsing and add to the sauce.
4. Remove the pot from the heat and stir in half the cheese.
5. Serve garnished with the remaining cheese.
