Assemble it
Spread chipotle mayo on the bread. Sprinkle the remaining bread slices with cheese. Top them with half of the chicken. Add tomato, spring mix salad, bacon, and 2 onion slices to each one.
Place the reserved bread on top of each sandwich half. Place both sandwiches in the panini press. Toast them until the cheese is melty and the bread is nice and toasty. Serve and enjoy!
