"Texas" Burgers

Fast-food chains have created regional burgers named after the Lone Star State:

McDonald's: Took note that Texans preferred burgers with mustard, onions and pickles and created the "Texas Homestyle Burger."
Wendy's: "Texas Double Cheeseburger" with two 2-ounce patties, mustard, onion, pickles, lettuce and tomatoes.
Burger King: "Texas Double Whopper," a traditional Double Whopper with mustard and jalapeños – no ketchup, no mayo.
