1 medium onion, finely chopped
2 cloves garlic, minced
1 tablespoon butter
3 cups tomato sauce (no salt added)
1 teaspoon oregano
1/2 teaspoon thyme leaves
1/2 teaspoon basil
1/4 teaspoon marjoram
1 (10-ounce) package frozen chopped spinach
1 cup (8 ounces) Wisconsin part-skim ricotta cheese
2 tablespoons grated Wisconsin parmesan cheese
1/4 teaspoon nutmeg
8 lasagna noodles, cooked and drained
For the sauce, sauté the onion and garlic in butter until tender. Add the tomato sauce and seasonings. Simmer 30 minutes.
Preheat the oven to 350°F.
For the filling, cook the spinach according to the package directions. Drain and squeeze out the excess water. Blend together the spinach, cheeses, nutmeg, and pepper until thoroughly mixed. Spread the mixture evenly along the entire length of each lasagna noodle. Roll each one and place on its side in a buttered shallow baking dish. Cover with sauce. Bake for 20 to 30 minutes or until heated through.
