Preheat the oven to 350°F. Line a large baking sheet with parchment or a nonstick baking mat.
Toss the pulled pork and ¼ cup of the barbecue sauce together in a bowl with tongs.
Add a layer of tortilla chips on the bottom of the sheet pan.
Next, add a layer of shredded cheese.
Spread the BBQ pulled pork on top of the shredded cheese.
Top the pork with the chopped onion and bell peppers.
Bake for 20-25 minutes, or until the cheese has completely melted.
Let cool for 5-10 minutes.
Drizzle with the additional barbecue sauce. Garnish with pickled jalapeno and cilantro.
Serve warm.
