These nachos are best eaten fresh and definitely will result in some soggy chips if you try to store them. So my best recommendation is to only make as many as you'll eat! If you do end up not finishing them and need to store, I recommend removing the toppings in storing the chips and toppings in separate containers. Then when ready to eat, re-bake the chips in the oven at 350* for 6-8 minutes. Then add back the toppings!
