what are hamburgers made out of?
Depends. Watch "Fast Food Nation" and you may not ever eat a burger at certain very popular fast food restaurants again. But if you make them at home hopefully they are made of beef.
Well it depends on where you get them. However they are supposed to be made from ground beef mixed with some ground fat. Some people put fillers in (some restaurants too) such as soy, eggs or breadcrumbs.
Good burgers are made of high quality beef.
Usually made of meat. There are beef, turkey, even pork and veal burgers.However, there are also Tofu burgers, and veggie burgers, neither have meat.
Disgusting dead cows.
Ground beef & turkey veal.
