Three sets of nachos.
First, the plain jane original created by some poor overworked waiter named Nacho when the kitchen was already closed and they had to feed a large late group of guests at the restaurant he worked at. Or so the legend goes.
These are simply individual chips with a generous amount of cheese on each and topped with a slice of pickled jalepeno.
Second, same as above but instead of just cheese, include first a layer of refried beans and meat of your choice.
Third, same as above but just meat and cheese.
People often load 12 ingredients onto a plate of nachos. I think it's better to do multiple plates and have a bit of variety between them.
Supplemental tips:
Buy a package of corn tortillas, cut into fourths and fry. They are far more sturdy than bagged chips. And tastier. Just remember to salt a bit after frying.
If you go the bean route, do them yourself. Canned beans are an atrocity. Buy a bag of dried pintos. Rinse well. Cup and a half of dry beans. A tablespoon or two of bacon fat, salt, half an onion, and a whole fresh jalepeno. Keep it simple. Most of the flavor will come from the pinto itself. You should remove the jalepeno after an hour and a half of cooking before it bursts, unless you want them spicy of course. Don't have bacon fat lying around? Two strips of bacon will do, raw. Boil then simmer, covered, on low heat for maybe three hours. Monitor the level of liquid, might have to add a bit after two hours. Crock pot overnight works fine too. Then mash them with a potato masher or something, might have to boil them down a bit to thicken.
Taco meat. Ground beef, fatty, like 80%. Salt the meat however mich you like. Cook it on high heat. A lot. Like burn it almost. Then keep cooking it. It should be loud and crackling. With lots of crusty bits like the outside of a burger. Once the pan develops a layer of crust pour water in the pan to deglaze. Then cook some more. All the while stirring and breaking up the meat into amall pieces. At some point cover and simmer. Can't over cook it. Just need to get to the point where remaining moisture bouls off. Seasoning: garlic, cumin, black pepper. If you have a chili powder you like add that too. Add seasoning after you add water.
