McDLT: The McDLT (McDonald's Lettuce and Tomato) was sold in a novel form of packaging. 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 container. The consumer was then expected to finalize preparation of the sandwich by combining the hot and cool sides just prior to eating.

I sure do miss actively participating in the creation of that bad boy...
