Preheat the oven to 350°F with a rack in the center. Line a baking sheet with parchment paper or foil (optional but it makes for easy cleanup).
Spread half of the chips in an even layer on the baking sheet and top with half of the shredded cheddar cheese, half of the Monterrey Jack cheese and half of the protein. Place the baking sheet in the oven and bake until the cheese is melted, 3 to 5 minutes.
Remove the baking sheet from the oven. Add the remaining chips, cheese and protein then return it to the oven and bake until the cheese is melted, an additional 3 to 5 minutes.
Remove the nachos from the oven and immediately top with the corn, guacamole, salsa, olives, jalapeños and cilantro. Serve immediately.
