I love serving this make ahead meal to my boys who are in the middle of football season and seem to be in a perpetual state of hunger. The meat sauce can be made ahead and has lots of onion and diced red pepper along with some red pepper flakes that provide a hint of heat. I use a six-ingredient Italian cheese blend and some. Marinated mozzarella balls just before heating in the oven. The individual baking dishes are a great way to save any extras that can get heated in the oven for another meal.
