Preheat oven to 350 degrees F.
Cut each zucchini lengthwise down the middle. Using a spoon or melon baller, scoop out the middle to create your "boat."
Place face up onto a baking sheet.
In a large skillet, heat additional olive oil over medium heat.
Add onion and cook for 5 minutes, or until onion starts to soften.
Add turkey, cooking until cooked through, and breaking up into small pieces as it cooks.
Add buffalo wing sauce, stirring to combine.
Fill each zucchini boat with ~¼ cup of buffalo turkey. You can definitely eyeball this, and it is very dependent on how large your zucchini is.
Top with shredded cheddar cheese.
Bake in preheated oven for 30 minutes.
Serve, topping with blue cheese and green onion.
Drizzle with additional buffalo wing sauce and/or ranch/blue cheese dressing if desired! It's definitely recommended!
