McDLT: The McDLT (McDonald's Lettuce and Tomato) was sold in a novel form of packaging.[20] The McDLT was introduced in the fall of 1984 as the Lettuce and Tomato Special. The meat and bottom half of the bun were prepared separately from the lettuce, tomato, American cheese, pickles, sauces, and top half of the bun. Both were then packaged into a specially designed two-sided styrofoam container. The consumer was then expected to finalize preparation of the sandwich by combining the hot and cool sides just prior to eating. It was discontinued between December 1990 and January 1991 due to environmental concerns with styrofoam
