Using a large skillet with a lid, brown the onions and garlic in olive oil until soft.

Add the beef to the skillet and brown the ground beef until beef is cooked through. This should take about 4-5 minutes.

Season meat with onion salt, oregano, and pepper while cooking.

Drain off any grease.

Stir can of tomato sauce and 1 1/3 cup water into the skillet and bring to a light boil.

Add the egg noodles and stir until all egg noodles are covered with sauce.

Cover and simmer for about 6-7 minutes or until noodles are tender.

Blend the Ricotta cheese, Parmesan cheese and salt.

Drop spoonfuls of the cheese on top of the noodles.

Sprinkle mozzarella cheese over all; cover and let cook for about 2-3 minutes until the cheese melts and is heated through.
