1Preheat the oven to 180°C (350°F).
Spread the tortilla chips on a baking sheet in an even layer.
Crack the eggs into a bowl and beat them until well mixed. Scramble the eggs in a non-stick skillet over medium heat until they are just set.
Evenly distribute the scrambled eggs over the tortilla chips.
Sprinkle the shredded cheddar cheese over the eggs and chips.
Scatter the cooked black beans on top of the cheese.
Place the baking sheet in the oven and bake for about 5-7 minutes, or until the cheese is melted and bubbly.
While the nachos are baking, dice the avocado, tomato, and green onions. Slice the jalapeno into thin rings.
Remove the nachos from the oven and immediately top with the diced avocado, tomato, green onions, and jalapeno slices.
Dollop the sour cream over the nachos and drizzle with salsa.
Serve immediately while hot and enjoy.
