The Mezzanine

Don't worry. At least half the fillings fall out the far side of the bun, so with most mouthfuls, you're mainly getting about four, maybe five flavours. As a brief guide, you can expect to lose most of the lettuce, possibly about half the tomato, and maybe a bit of the egg. This is why you don't throw away the wrapper - it acts as a catching plate for all the bits which fall out.
