Preheat your oven to 400°F (200°C).

In a large skillet over medium heat, add the ground turkey and diced onion. Cook for about 6-8 minutes until browned.

Incorporate the diced zucchini, sliced mushrooms, diced roasted red peppers, and minced garlic. Cook for an additional 3-4 minutes.

Add crushed tomatoes, marinara sauce, red pepper flakes, salt, and black pepper. Stir well and let simmer for about 10 minutes.

Bring a pot of salted water to a boil and cook the whole wheat ziti until al dente, approximately 7-8 minutes. Drain and cool.

Combine the cooked pasta with the Bolognese sauce and fold in half of the mozzarella and Parmesan cheese.

Transfer to a greased baking dish, spread evenly and top with remaining mozzarella and a sprinkle of Parmesan.

Bake for 30 minutes until the top is golden and bubbly. Let cool for 5-10 minutes before serving.
