This unique chicken lasagna is made with layers of lasagna noodles, green tomatillo salsa and tomato salsa, cilantro, mexican cheese, spinach, diced tomatoes, and cooked chicken. The tex-mex flavors make this delicious lasagna an extra-special meal your family will ask for again. To cut down on prep time, cook the chicken a day in advance or purchase a rotisserie chicken or fully cooked chicken strips.
