01 - Combine chicken breasts, chicken broth, smoked paprika, cumin, chili powder, garlic powder, onion powder, salt, and pepper in a medium saucepan. Bring to a gentle simmer over medium heat. Cover and cook for 18–20 minutes, or until the chicken is cooked through and tender.
02 - Remove chicken from the pan and shred using two forks. Return the shredded chicken to the pan, toss to coat in the remaining juices, and keep warm.
03 - Preheat oven to 400°F.
04 - Spread tortilla chips evenly on a large baking sheet or ovenproof platter.
05 - Distribute the pulled chicken over the chips, then sprinkle with cheddar and Monterey Jack cheeses.
06 - Scatter half of the diced red onion, jalapeño slices, tomatoes, and black olives on top.
07 - Bake for 8–10 minutes, or until the cheese is melted and bubbly.
08 - Remove from the oven and top with the remaining fresh onion, diced avocado, cilantro, and extra jalapeño if desired. Serve immediately with dollops of sour cream and lime wedges on the side.
