Prepare a baking sheet by adding a layer of parchment paper to the top.
Cover the parchment paper with the chips.
Sprinkle cheese on top of the chips.
Put the baking sheet in the oven on the middle rack and broil on low for about 7 minutes (watch them though). If you only have one broil setting then cook about 3 minutes, watching constantly.
While the cheese is melting over the chips in the oven, dice the green onions, lettuce, avocado, jalepenos, and cilantro.
When the cheese is melted, remove the baking sheet from the oven and sprinkle the black beans evenly over the top.
In this order, add the green onions, cilantro, lettuce, jalepeno nacho peppers, and avocado.
Layer the top with salsa and/or sour cream as you like.
Enjoy.
