The burger here is pure California: a quarter-pound of fresh beef, griddle-cooked and served on a toasted white squishy bun with American cheese, lettuce, onion, pickles and Thousand Island dressing. The dressing is made in-house using a recipe that was provided by the Kraft company back in the 1960s and still uses Kraft mayonnaise. According to Hamburger America, Pie 'N Burger goes through over a hundred pounds of the dressing a week. That is an awful lot of burgers, even if each one gets a generous smear of the tangy sauce.
