Sauce
1/4 cup olive oil
1 pound veggie ground
1 cup chopped onion
3 large garlic cloves, chopped
2 teaspoons dried oregano
1 teaspoon dried crushed red pepper
1 28-ounce can crushed tomatoes with added puree
1 14 1/2-ounce can diced tomatoes with green pepper and onion (do not drain)
Heat oil in heavy large pot over medium-high heat. Add sausages, onion, garlic, oregano and crushed red pepper and sauté until sausage is cooked through, mashing sausage into small pieces with back of fork, about 10 minutes. Add crushed tomatoes and diced tomatoes with juices. Bring sauce to boil. Reduce heat to medium and simmer 5 minutes to blend flavors. Season with salt and pepper. (Can be made 1 day ahead. Chill until cold, then cover and keep chilled.)
Filling
11/2 cups (packed) fresh basil leaves
1 15-ounce container plus 1 cup part-skim ricotta cheese
1 1/2 cups (packed) grated mozzarella cheese (about 6 ounces)
3/4 cup grated Parmesan cheese (about 2 ounces)
1 large egg
1/2 teaspoon salt
1/4 teaspoon ground black pepper
Using on/off turns, chop fresh basil leaves finely in processor. Add ricotta, mozzarella, Parmesan, egg, 1/2 teaspoon salt and 1/4 teaspoon pepper. Using on/off turns, process filling until just blended and texture is still chunky.
12 no-boil lasagna noodles from one 8-ounce package
3 cups (packed) grated mozzarella cheese (about 12 ounces)
