Use a bowl to mix the sour cream and crushed garlic in.
Place the chopped chicken on top of the lettuce leaves. Arrange the slices of mozzarella, cucumber, and tomato neatly beside the chicken. Spoon the garlic sour cream and pour onto the leaves. Season with a dash of salt and pepper.
Fold the lettuce leaves over the chicken filling and roll into wraps. Push a toothpick through the leaves to secure. Serve and enjoy.
