- Preheat oven to 375 degrees. 
- It a skillet over medium heat, add oil and cook the red pepper until browned and tender, about 3-4 minutes. Remove and set aside. 
- Reduce heat to medium-low and in the same skillet, add the diced onions and cook them until partially caramelized, about 8-10 minutes. 
- In a mixing bowl, add the cream cheese, sour cream, 1/4 cup of BBQ sauce, and ranch. Mix together until smooth and creamy. 
- Into the cream cheese mixture, fold in banana peppers, red pepper, red onion, chicken, and 1/2 the green onions and 1/2 the cheese. 
- Pour the mixture into an oven-safe skillet (I use cast iron). Smoothing it to out. Layer the top with enough barbecue sauce to evenly coat. 
- Add cheese on top and bake uncovered for about 20-25 minutes until it’s bubbly on the edges and cheese is melted. Half way through the bake time, sprinkle on the bacon pieces over the cheese. 
- Serve warm and melty with tortilla chips.
