Instructions

1. Preheat the oven to 355°F (180°C).
2. Heat the olive oil in a large skillet and cook the chicken breasts until golden on both sides. Place the chicken on a rimmed baking tray and bake in the oven until cooked through with an internal temperature of 160°F (71°C), approximately 15 minutes. Remove the chicken from the oven and allow to cool slightly before slicing into thin strips. Season the chicken strips with salt and freshly ground pepper, to taste.
3. While the chicken is baking in the oven, cook the bacon in the same skillet used for the chicken until crispy. Remove the bacon from the skillet and set aside.
   
4. Place 4 slices of Keto bread on 4 plates.
   
5. Place the soft lettuce leaves onto each of the 4 pieces, followed by thin slices of tomato. Top the sliced tomatoes with two pieces of bacon and the sliced chicken.
   
6. Gently place two of the dressed sandwiches on top of the other two dressed sandwiches. Place the 5th and 6th undressed slice of bread on top of the 2 dressed sandwiches. Cut each sandwich in half to make 4 triple-decker sandwiches.
