Heat your skillet over medium-high heat. Add the ground beef and cook, breaking it apart with your spoon, until it’s no longer pink and starts to brown, about 5-7 minutes. Drain any excess fat if necessary.
Stir in the drained kidney beans, black beans, diced bell peppers, and the entire can of diced tomatoes with green chilies. Mix everything together so the flavors start combining.
Sprinkle the chili seasoning mix over the beef and bean mixture, then pour in one cup of water. Stir well to combine. Reduce the heat to medium-low and let the chili simmer for 15-20 minutes, stirring occasionally until it thickens and the flavors meld.
While the chili simmers, spread the tortilla chips evenly over your baking sheet or oven-safe platter. This will be the crispy canvas for your chili masterpiece.
Once the chili is thick and flavorful, spoon it generously over the chips. Then sprinkle the shredded cheddar cheese evenly on top, ensuring every chip has a cheesy layer.
Place the baking sheet in a preheated oven at 375°F (190°C) for about 8-10 minutes, or until the cheese is melted and bubbly. Keep an eye on it to prevent burning.
Remove the nachos from the oven and immediately scatter the chopped green onions over the top. Add dollops of sour cream, and if desired, sprinkle sliced jalapeños.
Serve your Stadium Chili Cheese Nachos hot and fresh for maximum crunch and gooey goodness. Enjoy!
