Set oven to 420F.
Spray a nonstick skillet with olive oil and set on medium-high heat. Sauté red onion and bell pepper for 3 to 5 minutes, until the onion is brown and translucent.
Add the ground turkey. Chop and cook it up in the skillet using a wooden or rubber spatula. While it cooks, add in the seasonings and a pinch of sea salt & pepper. Cook until the turkey is no longer visibly pink, about 5 to 7 minutes. Set aside.
Beat eggs and egg whites together in a bowl.
To a small baking tin – or 5×5 casserole dish (sprayed with olive oil) – add chopped spinach, a serving of the ground turkey mix and your serving of eggs. Add about 8 veggie tots (or 9 sweet potato tots) to the top, then sprinkle on about 1/4 cup cheddar. Repeat for the remaining tins.
Bake for 25 minutes or until the egg has fully cooked.
