Top one slice of bread with the apple, chicken, and cheese. Assemble the sandwich and butter both sides.
In a medium non-stick pan over medium-high heat, grill the sandwich for 2 to 3 minutes, until the bottom is golden brown. Flip and continue to grill until the cheese is melted.
Remove from heat and allow the sandwich to cool down to room temperature before slicing it in half and packing it inside a lunch container.
To prevent the bread from getting soggy, add the grapes, almonds, and banana into separate compartments. Seal the container and pack it into a lunch bag with an ice pack.
