Make It Again Hamburger Casserole: I added diced tomato, garlic powder, italian seasoning, a pinch of red pepper flakes, salt, and pepper to the meat. I didn't have tomato soup. Instead, I added two cans of tomato sauce, 1/4 cup of sugar, a teaspoon of salt, and two tablespoons of cornstarch. Otherwise I followed the recipe. It was great!
