Instructions

Preheat oven to 350°. In a large skillet, cook sausage, mushrooms and garlic over medium heat 8-10 minutes or until sausage is no longer pink and mushrooms are tender, breaking up sausage into crumbles. Remove from pan with a slotted spoon. Remove drippings.
Remove stems from Swiss chard; coarsely chop leaves. In same skillet, heat butter over medium heat. Stir in flour until smooth; gradually whisk in milk. Bring to a boil, stirring constantly; cook and stir 1-2 minutes or until thickened. Add 3/4 cup cheese, parsley, oregano, lemon zest, salt and pepper; stir until cheese is melted. Stir in Swiss chard leaves.
Spread one-fourth of the cheese sauce into a greased 8-in. square baking dish. Layer with each of the following: two noodles, one-third of the meat mixture and one-fourth of the cheese sauce. Repeat layers twice. Sprinkle with remaining cheese.
Bake, covered, 45 minutes. Bake, uncovered, 8-10 minutes longer or until cheese is melted. Let stand 10 minutes before serving.
Freeze option: Cool unbaked lasagna; cover and freeze. To use, partially thaw in refrigerator overnight. Remove from refrigerator 30 minutes before baking. Preheat oven to 350°. Cover lasagna with foil; bake as directed, increasing covered time to 55-60 minutes or until heated through and a thermometer inserted in center reads 165°.
