• A surefire winner - many will worship you.
• I can't imagine adding eggs to my hamburger w/o the resulting burger tasting like meatloaf. If you use a good 80/20 chuck, you shouldn't need a binder like eggs in it. And if you're trying to cut back by using 90/10 and adding egg, you're actually adding more fat and cholesterol had you not used the 80/20.
