Cook the pasta according to the package instructions. Drain and set aside.
Heat up the pan over medium heat. Add some olive oil, sausage, onion, and zucchini. Cook for several minutes or until the onion has softened and the zucchini is fork-tender.
Season the mixture with some salt, pepper, red pepper flakes, and garlic. Stir and cook for about 30 seconds.
Turn off the heat and add the tomatoes, basil, cooked pasta, and another drizzle of olive oil. Stir to combine.
Serve the Pasta with Veggies and Smoked Sausage topped with Parmesan cheese and extra basil if desired.
Notes
Store leftovers in the refrigerator. This dish re-heats nicely in the microwave and is very tasty the next day.
