Buffalo Or Beef Burger

---

Buffalo tastes rich but is very lean - adding medium ground beef to it keeps these burgers juicy. We're fortunate to live near a buffalo ranch but if you don't & can't find it at the supermarket, a butcher may be able to order it for you - or you can substitute with all beef. This recipe comes from the rebel house restaurant in toronto which is known around town for its excellent buffalo burger.
