Place the tortilla chips evenly on a large sheet pan, making sure the entire pan is covered with chips. Top the chips with shredded cheese, black beans, and diced peppers. Place the nachos in the oven and bake until the cheese is melted, about 7-10 minutes.
While the nachos are in the oven, make sure you have all of your veggie toppings ready to go. Remove the nachos from the oven and top with tomatoes, corn, lettuce, cabbage, avocado, radishes, green onion, cilantro, and queso fresco. Serve immediately.
