The 4-Course Submarine Sandwich

The original idea of the sandwich was to produce a meal which could be consumed tidily without utensils, perhaps while engaged in some other activity. But why sacrifice quality? Why not take the original concept to its logical conclusion and put a 4-course meal on a sandwich? Exploit the spatially linear form of a submarine sandwich to mimic the temporally linear form of a multi-course meal. The sandwich becomes biased along its length, with one end clearly indicated as the starting end, which contains ingredients evocative of a soup course. As you eat along the sandwich, the soup ingredients give way to salad, and then to meat, and finally to dessert. Obviously, planning the dishes to compliment one another is important here, even moreso than in a traditional multi-course meal.
