The turkey lurking leftovers are kaput, and we're moving on to something thick with a little kick and appropriately jacketed in a toasty bun. The bison burger, FLIP burger boutique's December burger of the month, grazes our radar. FLIP adorns its tender, juicy bison patty Southwest-style with pepper Jack cheese, cilantro-lime mayo and two onion rings stacked to contain bison chili and seasoned sour cream. A perky cilantro sprig doubles as holiday greenery. Feliz Navidad, y'all.
