Butterfly each boneless, skinless chicken breast and cut each half into two to create 4 small pieces of chicken from each chicken breast. Brush each chicken piece with olive oil and sprinkle with salt.
Heat grill to medium heat and grill chicken pieces for 2 to 3 minutes on each side (or until the thickest part is 165 degrees F).
Cut cheese slices in half to create two smaller pieces. Top each slider bun with piece of grilled chicken, slice of tomato, cheese, bacon and lettuce.
