I don't like most meatballs. They're chock full of tasteless grains/breadcrumbs which dilute out a good flavor.
I like either meaty or a veggie (yes, without meat) vegetarian sauce. And I'd rather have this draped over anything but spaghetti, which I can't twirl properly on any fork to satisfy any of my Italian friends. Give me just about any other form of pasta noodle. (Yes, you are talking to someone who gnoshes down with Chinese OR Korean chopsticks with ease... I even had the chef come out from a kitchen at a Korean restaurant amazed that this white woman could do that... Okay, it wasn't a busy lunch.)
So... meat sauce or a meatless sauce that gets its flavor by not simply subtracting the meat. I mean, come on . Vegetarians (whom I cook for regularly) want flavors and such, too.
