You can also easily use the pre-made chicken strips from the supermarket's refrigerated section - they actually taste pretty good!
If you use raw chicken, for example, chicken breast fillets, you can start by placing the whole breasts in the pan and cooking them - they should not be fully cooked, as they risk becoming dry after the trip in the oven. Let them remain slightly pink in the center. Then shred the breasts using two forks and distribute the strips over the chips before placing them in the oven.
If you want to add jalapeños or olives, or both, just include them in the layers before putting it in the oven.
