Who knew my beloved takeout could be a casserole? This is a serious life hack!

For a vegetarian version, omit the ground beef and use a combination of tofu and extra mushrooms. For a bit of heat, add some red pepper flakes or a dash of hot sauce to the beef mixture. If you prefer a crunchier topping, consider adding crushed fried wonton strips or panko breadcrumbs on top before baking. You can also experiment with different cheeses or add some bean sprouts and snow peas for extra texture.
