Preheat the oven to 375 degrees.
Heat a large skillet over medium heat, add the oil, then add your ground turkey. Use a wooden spoon to break up the turkey meat as it cooks. Season with a pinch of salt and pepper, and stir occasionally and let it cook for 7-8 minutes, until it is cooked through and lightly brown.
Pour in the jar of red sauce, stir, and let it cook for 2-3 minutes to warm the sauce. Then remove from the heat and set aside.
In the meantime, slice the zucchini lengthwise and carefully scoop out the seeds and insides with a spoon. Place the zucchini boats on a large baking sheet.
Spoon the meat sauce into the boats to fill them up, then top with a few pieces of pepperoni and a sprinkle of cheese.
Bake for 25 minutes, until the zucchini has softened and cooked through, and the pepperoni is crispy.
Let them cool slightly and serve!
