Tom Pizzica travels to San Antonio, Texas, to a self-proclaimed outrageous restaurant, Marianito's Extreme Tex Mex Grill, where one diner challenges another group of diners to eat a seven-pound burrito in just one hour. Then he heads an hour west of Fort Worth, Texas to help the "outlaw chef" feed a bunch of working cowboys the old-fashioned way, off a chuck wagon with parts of the cow most folks won't eat. And for a breakfast of champions, he stops in at Shelby's Kitchen & Deli in Deerfield Beach, Fla., for a two-foot pancake topped with eggs, bacon, home fries, sausage patties, and toast.
