Prepare a grill fire to 350° using pecan or hickory for smoke flavor.
pat chicken dry with paper towels. Coat with olive oil and sprinkle with dry rub. We used 3 boneless chicken thighs that we had on hand.
Cook the chicken over indirect fire with the grill closed until they reach 165°.
Remove from grill, cool slightly and dice.
Add chopped chicken, cream cheese, shredded colby-jack cheese, diced jalapeños, garlic, salt and pepper to a bowl. Mix until well combined.
Slice the peppers in half, leaving the stem ends to form boats. If your peppers are too shallow to cut in half, you can just slice a bit off of one long side.
Fill peppers with chicken and cheese filling.
Sprinkle with cheese and bacon crumbles. Drizzle with bbq sauce.
Grill over indirect fire with the grill closed for 25- 30 minutes until filling is hot and bubbly and peppers are softened. The chicken is already cooked through, so there are no worries of bringing it to a specific temperature.
Remove from grill and serve immediately.
