Brown hamburger and onion in a large skillet.

Drain off any excess grease.

Add salt, garlic, Italian seasoning, basil, and sugar to the skillet.

Stir in tomato sauce and simmer for 20 minutes, stirring occasionally.

Cook lasagne noodles according to package directions.

While the sauce simmers and noodles cook, mix cream cheese, sour cream, egg, and chives in a bowl until smooth and creamy.

Preheat oven to 350°F (175°C).

In a 9x13 inch baking dish, layer cooked lasagne noodles.

Spread a layer of the cream cheese mixture over the noodles.

Spoon a layer of the hamburger mixture over the cream cheese mixture.

Repeat layers of noodles, cream cheese mixture, and hamburger mixture until all ingredients are used, ending with a layer of hamburger mixture on top.

Sprinkle shredded Mozzarella cheese evenly over the top.

Bake in preheated oven for 45 minutes, or until bubbly and cheese is melted and lightly browned.

Let stand for 10 minutes before cutting and serving.
