Natural Acres ground beef, both organic and from grass-fed cattle, is currently our least expensive ground beef, at $4.40/lb. It is sold in the freezer, top shelf. I like adding lots of chopped parsley and a little salt & freshly ground pepper to hamburgers. Gives them a little nutritional boost plus adding flavor.
Also in the freezer, perfect for grilling, are McDonald's Farm summer sausages and various other cuts of meat, including occasionally Dine's delicious hot dogs. So if you don't find what you want in the fresh meat area, check out the freezer.
