Everybody cheats on occasion. It's easy to grab a bag of frozen meatballs, brown them, then sauce and serve.
The question for me is why. Meatballs or polpette are the easiest quick meal - and if you plan ahead, you can make extra to freeze.
That way when you get home exhausted and wonder what's for dinner, you'll just have to reach in the freezer for a better meatball - homemade instead of store-bought.
