Bring a pot of salted water to a boil and toss your cubed chicken pieces. Leave them in there to cook and get nice and tender for about 10-15 minutes.
While that’s cooking, mix together your mayonnaise, grape halves, almonds, and truffle salt until combined.
Remove your chicken from the pot and let cool for a few minutes. Then, with two forks, shred your chicken. Add chicken to the salad mixture and mix until combined. Test for flavor and add more truffle if needed.
Place the mixture onto a slice of the Pane Turano Italian Bread, top with a few tomato slices and some lettuce, then the other bread slice. Cut in half and dig in!
