Make a large salami and cheese sandwich with lettuce, tomato, and mayonnaise on the bread, reserving the bread heels for later use. Cut the sandwich into 2-inch pieces. Arrange these in a snake curve on a platter. For the head, halve one heel and open it to make the snake's mouth.
Wedge 2 carrot strip "fangs" into the mouth to hold it open. Cut a piece of red pepper into a tongue shape and set it between the fangs. Add broccoli florets for eyes and radish slices for eyebrows. Use the remaining heel at the tip for a tail
