Cook ground beef in a saucepan over medium heat, breaking it up until almost no pink remains. Add 1 cup of water and taco seasoning. Continue cooking until water has cooked off. Set aside.
Meanwhile, lay tortilla chips in an even layer on baking sheet. Add ground beef, black beans, corn, and black olives. Sprinkle both cheeses on chips, ensuring they are evenly covered.
Bake for 12-15 minutes or until cheese is melted and bubbly. Meanwhile, prepare the fresh toppings.
Once nachos come out, top with fresh tomatoes, jalapeno slices, sour cream, and cilantro. Serve with salsa, pico de gallo, or guacamole.
