Organic beef can be very expensive, so a lot of people either avoid it to save money or simply can't afford it.
However, here is an option. In the supermarkets that I shop at, there is a section in the meat department marked "manager's special" or "clearance". It's meat that is getting close to it's sell-by date. I can almost always find a brisket or some cut of beef, and sometimes pork or chicken. Often the pork is a thin cut pork chop or pork chops that just aren't very even and don't look appealing. The bargain prices can be pretty astounding, and the meat is perfectly good, especially for grinding up.
So I buy the cheap beef or pork, and make my own ground beef. If I have a lot, I use the grinder attachment on my stand mixer. If I'm just making a small amount, I cut the meat up into cubes and just pulse it (important to use the pulse button) about 10 or 12 times and when it's done I have ground beef.
That way you can customize the beef. If I'm making Italian meatballs I'll add in some herbs, garlic, and use a combination of beef and pork, making sure to use a little pork fat for taste. If I'm making burgers, I add in Worcestershire sauce and garlic. For meatloaf: beef, pork and veal. For taco meat, some chilies and cumin, etc.
And I always know exactly what is in the ground beef I serve. And it only takes a few seconds, and it's much cheaper than packaged ground beef.
And yes, to answer your question, I'm mad about that pink slime!
