Brown meat, drain well, then add tomato sauce, garlic, sugar, and salt, simmer over low heat for 15 minutes
Prepare noodles according to package instructions, drain, then layer in the bottom of a 9x13 pan
Combine cream cheese, sour cream, & scallions, set aside
Add tomato sauce mixture over the noodles, then spread the cream cheese mixture over the sauce, spreading evenly
Sprinkle shredded cheese over the top, Bake at 350 for 20-30 minutes or until casserole is bubbly and cheese is melted
Let stand for 10 minutes before serving
You can easily double the recipe and make a second pan to stick in the freezer or give to a friend. This casserole actually tastes better made a day ahead BUT is still delicious if made & eaten in the same day.
