Place 1 Tbsp of Barbecue Sauce on each chicken breast, make sure it covers at least one side of the chicken.
Warm the grill up to medium-high heat and place the chicken breast on the grill. Let this grill for 10-20 minutes on each side or until the chicken reaches an internal temperature of at least 165*.
When the chicken is done, set aside or place on top rack of the grill to keep warm.
Cut the romaine lettuce in half lengthwise, place it seam side down on a clean portion of the grill.
Let this grill for about 2-3 minutes on each side until it begins to wilt.
Place each piece of romaine on a plate, then top each salad with 1 chicken breast, 3 slices of tomato, 1/8 cup tortilla strips, and 1/8 cup shredded cheese.
Lastly add 1 Tbsp of barbecue sauce to each salad and serve.
