Mix all wet ingredients (meat, milk, egg) until combined, then incorporate breadcrumbs and seasoning. Add 1 tablespoon of MID'S Meat Sauce if you want your meatballs to be extra moist.
Roll 14 meatballs with the mixture.
Add one jar of MID'S Meat Sauce into a large, deep skillet. Add meatballs and spoon sauce on top of each one.
Cook meatballs on medium high until the sauce begins to bubble, then turn the heat down to medium-low. Simmer uncovered for an hour and a half.
Once finished, add another jar of MID'S Meat Sauce to the skillet and heat through.
Serve with (or without) spaghetti.
