First, turn zucchini into noodles with a spiralizer. Break the noodles up into smaller sections of 6-8 inches with your hands or scissors. Using paper towels to wrap around the noodles, squeeze the noodles to get some of the water out of them. Set aside.
Heat a large skillet over medium-high heat. Once hot, add in sausage to cook. Break it into small chunks and cook, stirring occasionally, until it is browned and some crispy bits have formed throughout, about 8-10 minutes.
While the sausage is cooking, cut up bell peppers, onion and garlic as noted.
Once the sausage is cooked, remove it from the skillet and place in on a plate for later.
Preheat oven to 375 degrees Fahrenheit.
In the same skillet over medium-high heat, add in onions and peppers to cook, stirring frequently. Cook until they begin to soften, about 3-4 minutes. Add in garlic and cook for 1-2 more minutes.
Add the pasta sauce, cooked sausage and basil to the skillet. Stir everything together to mix well. Turn heat down to medium-low and allow the pasta sauce to to heat up for a few minutes.
Place the noodles in a 9x13 baking dish. Pour the sauce all over the noodles to cover evenly.
Top with cheese (optional) and bake for 15 minutes, or until the cheese is melted and the noodles are warmed through. Remove from the oven, serve and enjoy.
