My mom used to put margarine on both slices before the mustard on one side and the Miracle Whip on the other. The margarine keeps the mustard and Miracle Whip from soaking through the bread, while it sits in the bag on the shelf for four hours.

Maybe it also helps to keep the bread from sticking somehow, because I only had that happen when I ate at a friend's house.

I hate it when stuff gets stuck to my oof

mmdmmffgggfhhh

Gotta wash it down with that box of mystery 1% chocolate milk

Americans see a sandwich, a European sees a picture with no actual bread, no actual cheese and no actual meat.
