Preheat the oven to 400 degrees. Line a baking sheet with aluminum foil or parchment paper, or lightly mist it with cooking spray.

Slice each zucchini in half lengthwise. Using a spoon, scoop out the center of each zucchini forming a “boat” shape, leaving about ¼” thick around the edges. Sprinkle zucchini with salt and pepper and transfer it, hollow side up, to the prepared baking sheet. Set aside.

In a large skillet, cook the sausage over med-high heat, breaking it up with a spoon until it is cooked through. In a large bowl, mix the feta, pine nuts, tomatoes, scallions, oregano and sausage and stir until combined. Spoon the mixture evenly into the zucchini “boats” and place in the oven. Bake for 15-18 minutes until cheese is slightly melted and zucchini is cooked through.
