Nachos aren't always a finger food, since they often become overwhelmed by toppings and become too soggy to pick up. You can solve this problem in several ways. The first is to make a layered nacho dip with seasoned ground beef, refried beans, salsa and cheddar cheese, bake it, top it with sour cream (and perhaps jalapeño and onion) and use it to neatly dip tortilla chips. The second is to carefully lay out the tortilla chips on wire racks so they don't overlap, place a jalapeño slice and some onion on each, top them with cheese and bake, so that every chip stays separate, neat and relatively grease-free. Once the cheese has melted, dip the chips in salsa, guacamole or sour cream.
