Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or aluminum foil.
Arrange a single layer of tortilla chips on the prepared baking sheet, ensuring they overlap slightly.
Sprinkle a generous amount of shredded cheese evenly over the tortilla chips.
Add black beans, diced tomatoes, and sliced jalapeños on top of the cheese.
Place the baking sheet in the oven and bake for 10-12 minutes, or until the cheese is melted and bubbly.
Remove from the oven and garnish with dollops of sour cream, guacamole, and salsa.
Optional: Add cooked ground beef, shredded chicken, diced onions, or cilantro for extra flavor.
Serve immediately and enjoy your delicious homemade nachos!
