It's not an Italian dish (it's an invention of Italian-Americans, poor immigrants from southern Italy who found they could afford meat in America), and it gives adults heartburn, but American kids seem to love it and it's easy to make.
I loved it as a kid, but now I feel it's an unpleasant meal. At least, we have evolved beyond Chef Boyardee. Here's Easiest Spaghetti and Meatballs.
One genuine Italian touch: Crazy Martha says to throw the drained pasta into the meat and sauce in the saucepan. That's the right way to do it. Pasta in the sauce, not the sauce on top of the pasta.
