Step 1

Preheat the oven to 400°F.

Step 2

Crack the eggs and egg whites into a large bowl. Add 1/4 teaspoon of the salt and a pinch of fresh cracked pepper and beat until blended. Mix in cheese.

Step 3

Heat a 10-inch nonstick oven safe skillet over medium heat.

Step 4

Add the oil and onions to the pan and cook until the onions are golden, 5 to 6 minutes.

Step 5

Add the sweet potatoes and thyme, season with 3/4 teaspoon salt, garlic powder, paprika and pinch of black pepper. Cover and cook the sweet potatoes over medium-low heat, stirring occasionally, until crisp and tender, about 12 minutes.

Step 6

Add the chopped turkey to the skillet and stir to combine. Add the spinach, and cook until wilted, about 2 to 3 minutes.

Step 7

Pour the egg mixture into the skillet. Reduce the heat to low and cook until the edges are set, 6 to 8 minutes.

Step 8

Transfer the skillet to the oven and bake until the frittata is completely set and cooked through, 8 to 10 minutes. Remove from the oven and cut into 6 wedges and serve.
