Brown ground beef in a large skillet over medium heat. When fully cooked, sprinkle with taco seasoning and add 3/4 cup water. Bring to a boil, then turn heat down to low and simmer for 10 minutes.
2.
Preheat broiler to high. Line a large (11x17) baking sheet with aluminum foil.
3.
Arrange half of the tortilla chips in one layer on the baking sheet. Sprinkle with half of the cooked taco meat, onions, tomato, olives, and jalapeno; top with half of the cheese.
4.
Repeat layers with remaining ingredients.
5.
Broil about 4 inches from the heat source for about 3 minutes to melt the cheese and brown the top layer slightly.
Tip
If you don't like vegetables on your nachos skip everything but the taco meat, cheese, and chips.
