So if I want to eat nice meat cuts ground up, without getting slime, what do I do?
(1) buy a meat grinder, or
(2) go to a butcher (often even a grocery store butcher) that lets you select a cut and have it ground.
That's true even without the slime issue, because “ground beef” isn't coming from “nice cuts” with Abby particular consistency.
ground sirloin
ground chuck
ground round
etc.
I've personally largely switched to veggie ingredients for Lasagne and Moussaka. That was for taste reasons too but the health benefits are a nice bonus ;)
I eat a healthy and well balanced diet and I honestly don't understand that way of thinking from my fellow carnivores.
