01 - Preheat your oven to 400°F. Line a large baking sheet with parchment paper or foil for easy cleanup.
02 - In a mixing bowl, toss the shredded chicken with buffalo sauce until evenly coated throughout.
03 - Spread tortilla chips in an even layer across a large oven-safe platter or baking sheet, slightly overlapping for a sturdy base.
04 - Distribute the buffalo chicken evenly over the tortilla chips, ensuring every chip gets some coverage.
05 - Sprinkle shredded cheddar and mozzarella cheeses evenly over the entire surface, covering the chicken and chips.
06 - Bake for 10 to 12 minutes, or until the cheese is fully melted, golden in spots, and bubbling.
07 - Remove from the oven and immediately top with sliced green onions, diced tomatoes, crumbled blue cheese if desired, and jalapeño slices. Drizzle with ranch or blue cheese dressing and serve right away.
