This is a very basic recipe for a bologna (baloney) sandwich. See variations for different ways to prepare it.
16 slices of bologna
1 oz brown prepared mustard
1 Kaiser bun, sliced in half
On one slice of the bun, pile the bologna slices in the shape of a Venn diagram, alternating between those on the left and those on the right, so that your Venn diagram is made of bologna that hangs off the edges of the bottom of the Kaiser bun.
Smear brown mustard on the soft part of the other half of the bun. Top sandwich with the bun.
