Preheat oven to 350 degrees Fahrenheit. Grease a 9x13 inch baking dish and set aside.
In a large skillet brown the hamburger of over medium heat. Drain off any excess grease.
Add the onion, garlic, 1 Tbsp parsley flakes, garlic salt, oregano, tomato sauce to the skillet and simmer 30 minutes.
Meanwhile in a large bowl combine cottage cheese, eggs, salt, 2 Tbsp parsley flakes and Parmesan cheese.
When the meat mixture is done simmering spread ½ c. of hamburger mixture on the bottom of prepared pan. Place three prepared lasagna noodles side by side on top of meat mixture so they don't overlap. Top with half of meat mixture, half of cottage cheese mixture then half of Mozzarella cheese. Repeat layer except leave off the Mozzarella cheese.
Bake for 45 minutes in the preheated oven at 350 degrees Fahrenheit.
Remove from oven and top with remaining Mozzarella cheese.
