In a bowl, mix together the chipotle peppers and mayonnaise. Add the lime juice and salt & pepper and stir. Grill the chicken breasts and season with salt and pepper. When the chicken is about to be taken off the grill, top each chicken breast with a slice of pepperjack cheese. Spread a generous amount of the chipotle mayo onto each piece of bread. Top with the cooked chicken breast and then top with pickled jalapeno peppers, tomatoes, avocados, spinach and bbq sauce (if desired).
Notes
HEALTHIER OPTION: Serve bunless on a whole wheat bun. Use lowfat mayonnaise.
