Delicious Spinach and Turkey Lasagna

Preheat an oven to 375 degrees F (190 degrees C).

Bring a large pot of lightly salted water to a boil.

Cook lasagna noodles in boiling water for 8 to 10 minutes.

Drain noodles, and rinse with cold water.

Heat the olive oil in a skillet over medium heat.

Stir in the onion; cook and stir until the onion has softened and turned translucent, about 2 minutes.

Add ground turkey and cook 5 to 7 minutes more, stirring to break up any large chunks of meat.

Stir in tomato sauce, mushrooms, Italian seasoning, black pepper, and garlic powder.

Simmer for 2 minutes and season to taste.

Combine spinach, ricotta, and nutmeg in a large bowl.

To assemble, arrange 3 noodles lengthwise in the bottom of a greased 9x13 inch baking dish.

Spread with 1/3 the ricotta mixture, 1/3 of the turkey mixture, and 1/3 of the mozzarella.

Repeat layers, ending with remaining mozzarella.

Bake in preheated oven for 25 minutes.

Cool for 5 minutes before serving.
