Dice the tomato and red onion. Slice the jalapeño. Rinse and drain the black beans. Shred the cheddar cheese.

Preheat the oven to 350ºF. Whisk together the eggs, salt, and pepper in a large bowl.

Melt the butter in a large non-stick skillet over medium heat. Once hot, add the whisked eggs and gently stir and fold until the eggs are mostly set, but still slightly wet.

Line a large baking sheet with parchment paper. Spread half of the tortilla chips over the surface, then top with half of the eggs, half of the black beans, and half of the shredded cheese.

Repeat with a second layer of chips, eggs, beans, and cheese.

Bake the nachos in the preheated oven for 5-7 minutes, or until the cheese is melted.

Remove the nachos from the oven and top with the remaining fresh ingredients: tomato, onion, jalapeño, and sour cream. Serve hot.
