The $1 side will be available through March. The fries also come Supreme for $2.49 or Bell Grande for $3.49 with toppings, like beef, pico de gallo and sour cream.

Taco Bell said it plans to introduce 20 new $1 menu items this year, as many of the major fast-food chains continue to focus more on their value menus. On Jan,. 4, McDonald's launched its $1 $2 $3 Dollar Menu; Burger King already has the Value Menu and Wendy's has the Right Price, Right Size Menu.

In August, Taco Bell rolled out the Naked Egg Taco, which uses a fried egg as the taco shell.

Taco Bell is owned by Lousville, Ky.-based Yum! Brands, which also owns Pizza Hut and KFC.
