Preheat oven to 350 degrees. Line a baking sheet with foil then place a cooling rack on top and spray with nonstick spray.

Slice zucchini in half lengthwise then use a small spoon to scoop out seeds, creating a well down the center. Mist or brush zucchini halves on both sides with extra virgin olive oil then season both sides with salt and pepper. Place zucchini cut-side down on the cooling rack then bake for 15 minutes (if your zucchini are bigger or smaller than 10oz, add or subtract a couple minutes so you don’t end up with under-cooked or soggy zucchini boats.)

Meanwhile, brown sausage in a medium-sized skillet over medium-high heat then add tomato and basil, and saute until warmed through, 1 minute. Fill zucchini with sausage mixture then bake for another 10 minutes. Top zucchini with mozzarella cheese then broil until melted and serve.
