Preheat oven to 375°F.

Spray a 9" x 13" baking dish (or something close to this size) with nonstick spray and set aside.

Shred sweet potato using a food processor with shredding attachment or by hand. Set aside.

Cook turkey or beef in a large pot (at least 4 quarts) over medium-high heat using a wooden spoon to break into pieces. Cook until no pink remains. Drain off extra grease.

Add sweet potato, onion, red pepper, jalapeño, garlic, tomatoes (with juice), chili powder, paprika and salt. Cook until onions are translucent, about 5 to 7 minutes, and tomato juice has absorbed.

Add spinach to pot and cook for about 2 minutes or until spinach wilts.

Beat eggs in a large bowl.

Add meat and vegetable mixture from pot to the eggs along with 1 cup of cheese and 2-1/2 tablespoons cilantro. Stir until well mixed.

Pour into prepared baking dish pan and spread evenly along the bottom. Sprinkle remaining 1/2 cup cheese and 1/2 tablespoon cilantro on top.

Place in preheated oven and bake for 30 to 40 minutes or until middle of casserole is set (not jiggly) and edges are lightly browned. Remove from oven and allow to cool for 5 minutes.
