Place the turkey, celery and green onions in a medium bowl. Add in any of the options at this point if desired.
Combine the mayo, lemon juice, mustard, sugar and salt and pepper. Adjust the seasonings to your liking. Mix into the bowl of turkey meat until everything is coated completely.
Use as a sandwich filling or eat with lettuce cups, or on top of a bed of lettuce.
Notes
Use low fat mayo if desired
This will only last one day in the fridge before it gets watery, so this is best eaten the day you make it!
