Preheat oven to 375°F (190°C).

Season chicken breasts with salt and pepper. Cook in a skillet with olive oil over medium heat for about 6-8 minutes per side until golden brown and cooked through.

Allow chicken to rest briefly, then shred with two forks.

On a large baking sheet, layer tortilla chips, followed by shredded chicken, cheddar cheese, and jalapeños.

Bake for 10 minutes until cheese is bubbly and melted.

Remove from oven; drizzle with sour cream and guacamole, garnish with cilantro if desired.
