Toast the bread slices until golden and firm.

In a small bowl, combine mayonnaise and basil pesto to create the spread.

Place three slices of toasted bread in a row for each sandwich.

Spread the pesto-mayonnaise mixture evenly on one side of each bread slice.

Layer 4 oz of turkey and 2 slices of provolone on the first bread slice.

Place the second bread slice on top of the cheese.

Layer 3 slices of crispy pancetta, tomato slices, and shredded lettuce on the second slice.

Drizzle red wine vinegar and sprinkle oregano over the lettuce and tomato layer.

Place the third bread slice on top, spread-side down.

Secure the sandwich with four decorative picks and slice diagonally into quarters.
