Start by preheating your oven to 350 degrees Fahrenheit.
Cut off the tops of the peppers and scrape out the cores and as many of the seeds as you can get at. Lay the emptied peppers onto the aluminum sheet onto your baking metal tray.
Place the tray with the peppers in the oven once it reached the desired temperature. Leave in the oven for approximately 30 minutes.
While the peppers are baking for a while, time to start putting together the filling! We’ll start with the chicken. This is actually more simple than it sounds. Clean the chicken breasts by removing any excess fat and slime, and place them one by one in your steamer. Don’t overfill your steamer as this will cause the chicken to cook unevenly. Once your steamer is filled and the chicken breast slices are evenly spaced out, add the lid and pop in the microwave for 1 to 1 and a half minutes. It is OK if the chicken breasts are slightly under-cooked and you still see some slight pinkish areas. The chicken will fully cook later when in the oven. For now, we want it moist enough to break apart.
The easiest way for me to pull the chicken is to cut each breast slice in thirds. Then with a knife and fork (or two forks), hold down the piece and begin pulling the chicken apart. This may take some getting used to but you should see that the chicken meat breaks apart a certain way. When you see this you’ll want to break the chicken parallel to how the pieces naturally tear.
Once all the chicken is steamed an pulled, place in mixing bowl.
Next, chop up the mushrooms into small cubes. Do the same with the mozzarella. Place these chopped ingredients in the mixing bowl with the pulled chicken.
Finally add the cups of Cheddar cheese along with the BBQ sauce. Mix well.
After 30 minutes, take out the peppers from the oven. They should look a bit wrinkly and dried out on the ends. Let cool for a bit. You can even stick them in the fridge to cool faster.
Once the peppers have been cooled. Add Aluminum foil inside your bread loaf tray. Once by one, start stuffing the peppers and placing them upright inside the bread loaf tray. Doing this will allow the peppers to drain and keep the mixed ingredients intact and prevent spilling.
Once each pepper is filled to the brim, put those bad boys back in the oven and bake for another 25 minutes.
