Prepare the Salmon: Aggressively season the salmon filet with salt. Heat a cast iron skillet and sear the salmon on both sides until it achieves a golden color. Remove from the pan and flake the cooked salmon.
Cook the Eggs: In the same skillet, soft scramble the whisked eggs. Remove the scrambled eggs from the heat.
Make the Pico de Gallo: Combine all the Pico de Gallo ingredients (diced tomatoes, onion, minced jalapeño, and chopped cilantro) and mix thoroughly.
Assemble the Nachos: Arrange the tortilla chips on a baking sheet. Layer the chips with some of the fresh Pico de Gallo, followed by the Monterey Jack cheese, scrambled eggs, flaked salmon, and halved black olives.
Bake and Finish: Bake the nachos until the cheese is just melted. Remove the nachos from the oven, finish with a fresh squeeze of lemon juice, and top with the remaining fresh Pico de Gallo.
