Heat olive oil in a large skillet over medium heat.
Add diced green bell pepper, zucchini, and sliced mushrooms to the skillet. Cook for 5 minutes, stirring occasionally, until vegetables begin to soften.
Add minced garlic to the skillet and cook for 1 minute until fragrant.
Push the vegetables to the side of the skillet and add ground turkey to the center. Break it apart with a spatula and cook for 7-8 minutes until browned and cooked through.
Mix the turkey and vegetables together in the skillet.
Season with dried oregano, dried basil, smoked paprika, red pepper flakes, salt, and black pepper. Stir well to combine all ingredients.
Cook for an additional 2-3 minutes to allow flavors to meld.
Remove the skillet from heat and sprinkle grated Parmesan cheese over the top.
Garnish with chopped fresh parsley before serving.
