In a food processor, combine mayo and chipotle chillies. Whiz until smooth and set aside.
To make the sandwich, spread one side of each piece of toast with the mayonnaise.
Assemble in this order: On the bottom slice of toast, add half the spinach, then one slice of turkey, then half the tomato, then half the bacon, then one slice of the Swiss cheese.
Top with the second slice of toast, mayonnaise side down. Spread the top of the middle slice of bread with more of the chipotle mayonnaise.
Top with remaining spinach, then the sliced avocado, then three slices of turkey, then more tomato, the other slice of cheese, the remaining bacon, and the fried egg.
Top with the third slice of bread. Slice diagonally into quarters, holding each quarter together with a toothpick.
