Begin by preheating your oven to 375°F applying and apply grease to a 9x13-inch baking dish.
Combine the diced sweet potatoes with olive oil, salt, and pepper. Arrange them uniformly in the baking dish and bake for a duration of 15 minutes.
While the sweet potatoes bake, cook the turkey sausage in a skillet over medium heat until browned. Add the onion and bell pepper, cooking until softened.
In a bowl, whisk together the eggs, milk, garlic powder, and paprika.
Remove the sweet potatoes from the oven and layer the sausage mixture on top. Pour the egg mixture over everything.
Sprinkle with cheese (if using) and bake for 20-25 minutes, or until the eggs are set.
Garnish with fresh herbs and serve warm.
