Ingredients:
– 1 pound ground beef 
– 1 tablespoon olive oil 
– 1 small onion, diced 
– 2 cloves garlic, minced 
– 1 packet taco seasoning 
– 1 cup water 
– 1 bag tortilla chips 
– 1 cup shredded cheddar cheese 
– 1 cup shredded Monterey Jack cheese
– 1 cup black beans, drained and rinsed 
– 1 cup corn kernels (fresh or frozen) 
– 1/2 cup sliced black olives 
– 1/2 cup diced tomatoes 
– 1/4 cup chopped fresh cilantro 
– Sour cream and salsa for serving (optional) 
Preparation:
1. Cook the beef: Heat olive oil in a skillet over medium heat. Add diced onion and cook until softened, about 3-4 minutes. Add minced garlic and cook for another 1 minute. Add ground beef and cook until browned, breaking it up with a spoon. Drain excess fat.
2. Season the beef: Stir in the taco seasoning and water. Simmer for 5-7 minutes, or until the mixture thickens and is well combined. 
3. Prepare the nachos: Preheat your oven to 375°F (190°C). Spread tortilla chips evenly on a baking sheet or oven-safe dish. Sprinkle with half of the cheddar and Monterey Jack cheese. Top with the seasoned beef, black beans, corn, and remaining cheese. 
4. Bake the nachos: Bake in the preheated oven for 10-12 minutes, or until the cheese is melted and bubbly. 
5. Add toppings: Remove from the oven and top with sliced black olives, diced tomatoes, and chopped cilantro. Add sour cream and salsa on the side if desired.
