Preheat oven to 350º F. Line a baking sheet with foil or parchment paper. Arrange the tortilla chips in a single layer on the prepared baking sheet and set aside.
Add the ground beef to a medium skillet set over medium heat. Sprinkle on cumin, chili powder, salt and pepper. Cook, stirring frequently, until all of the meat is brown, about 5 minutes. Stir in the minced garlic and cook about 2 more minutes. Remove the skillet from the heat.
Remove the meat mixture from the skillet using a slotted spoon and arrange it on top of the chips. Then, top with the cheeses and the the black beans. Place the sheet pan into the preheated oven and bake until the cheeses have melted, about 5 - 7 minutes. Remove from the oven and top with peppers, green onions, salsa, sour cream, and avocado. Squeeze two lime wedges over the top of the nachos and serve the remaining lime wedges on the side.
