This is probably common knowledge to many of you, but I thought I'd pass it along to those of you who are interested.
I was in Publix doing the usual drooling over the different meats deciding what to cook and the Meat guy came out with a tray and started plucking all of the best steaks with specific dates off the shelves. Greenwise Choice strips, ribeyes, and only of the most expensive stuff. I asked him, surely you're not throwing all that away?! He replied: no, that that's what they always use to make the Market Ground Beef.
I started buying Market Ground from then on, and I like it much better than the ground sirloin, chuck, and other more expensive stuff I was getting previously.
