Dice the tomato and red onion. Slice the jalapeño. Rinse and drain the black beans. Shred the cheddar cheese.
Preheat the oven to 350.
Whisk together the eggs, salt, and pepper in a large bowl.
Melt the butter in a large non-stick skillet over medium heat.
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, 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 from oven and top with fresh ingredients: tomato, onion, jalapeño, and sour cream. Serve hot.
