Instructions: Steam spinach until tender; press out excess moisture and chop coarsely. Saute mushrooms, onions and minced garlic in olive oil over medium-high heat until onions are tender; drain excess liquid and cool.

Mix ricotta cheese, 2/3 cup Parmesan, egg, salt, pepper, basil and oregano in large bowl. Add cooled spinach and mushroom-onion mixture and mix on low speed until just blended.

Cook lasagna according to package directions; rinse under cool water and drain thoroughly. Place four lasagna strips in bottom of lightly oiled 9- by 13-inch pan, overlapping slightly. Top with 2 cups of spinach filling. Sprinkle with 1 1/2 cups shredded cheese and 1/3 cup Parmesan. Repeat layering two more times and top with remaining four lasagna strips. Spread 1 cup of Mariana or tomato-cream sauce over top and cover tightly with foil.

Preheat oven to 350 degrees and bake, covered, for 1 hour. Remove from oven and keep warm at least 30 minutes before cutting. Top with extra Parmesan cheese. (Can be refrigerated a day in advance of baking if desired.)
