Preheat the oven to 350 degrees Fahrenheit.
Prepare the cheese sauce by stirring together cooked ground beef (grease drained), velveeta (cut it into cubes so it will melt quicker), Rotel and green chiles in a large skillet over medium heat until the cheese melts completely. Remove it from the heat and stir it intermittently while you prepare the rest of the recipe.
Pour tortilla chips into a big sheet pan and spread them out evenly.
Sprinkle shredded cheddar evenly over the chips. Then sprinkle olives, diced red onion and black beans over.
Bake for 7-10 minutes, or until toppings are warm and cheese is melted.
Pour warm cheese sauce evenly over the chips, then add your favorite toppings (from the list above or others) and serve immediately.
