Heat broth in saucepan and keep warm while preparing remaining ingredients.
Heat oil in large sauté pan Add sausage, sauté until browned, 10-12 minutes per side. Transfer sausage to paper towel lined plate. When cooled, slice into 1/2 inch rounds and set aside.
In the sausage pan sauté fennel and onion until they begin to soften and brown (about 5 minutes). Add garlic, pepper flakes and thyme and cook stirring constantly for 2 minutes. Transfer vegetables to a bowl.
Add orzo to the sauté pan, stirring to coat pasta with residual oil in the pan; cook 2 minutes.
Deglaze pan with wine. Add 1 1/2 warm broth to orzo; cook stirring constantly until broth is nearly absorbed; another 5 minutes. Add remaining 1 cup broth; cook and stir until liquid is fully absorbed.
Stir in sausage slices, vegetable mixture, then add parmesan, butter, parsley, lemon zest and chopped fennel fronds. Season with salt and pepper.
In large heavy pan, lightly brown beef and onions in oil. Add tomatoes (with juice), tomato paste, water, parsley, salt, garlic powder, pepper and oregano. Simmer uncovered about 30 minutes. Mean while cook lasagna noodles as directed. In 9 1/2" X 13" baking pan spread about 1 cup of sauce, then alternate layers of noodles, sauce, cottage or ricotta cheese, mozzarella, Parmesan, hard-boiled eggs and zucchini ending with sauce, mozzarella and Parmesan. Bake at 350 degrees for 40 - 50 minutes or until slightly browned and bubbling.
Boil milk, water and butter. Cool to 110 degrees.
