How to Make It
Preheat oven to 500°F. Line a large rimmed baking sheet with aluminum foil. Arrange layers of chips, beans, pork, and cheese on prepared baking sheet. Bake in preheated oven until cheese is melted and chips are lightly browned, about 5 minutes.
Meanwhile, stir together sour cream and lime juice in a small bowl. Set aside.
Remove nachos from oven; immediately sprinkle with avocado, tomato, corn, jalapeño, and cilantro. Drizzle with sour cream mixture. Serve immediately.
