Start off by gathering essential ingredients such as grilled chicken, whole wheat bread, mayonnaise, lettuce, onions and tomatoes.
Shred or slice your cooked chicken into bite-sized pieces.
For an added crunch and extra flavor, lightly toast your bread.
Spread a generous layer of mayonnaise on one slice of bread.
Start with a layer of lettuce, onions and tomatoes on one slice of bread, and chicken on the other slice.
Add some extra toppings like grated cheese and avocado.
Close the sandwich with the second slice of bread, press lightly, and slice in half. Serve with a side of chips.
