I can go with you on the highest and best use of ground beef is to make a hamburger - specifically what I was talking about is crumbled fried ground beef.
There was a time when I used to eat pizza, and even make it. It started with a very thick, deep dish crust made from scratch, then next was a layer of sliced mozzerella covering the whole thing, then the hamburger (about a pound per pizza), then the mushrooms and pepperoni, and then cover everything with lots of pizza sauce. The end product would be about an inch and a half thick, and the hamburger would pick up the flavor of the sauce and pepperoni.
I suppose if you went sauce, cheese, toppings, then indeed, the hamburger would be flavorless.
