You can use whichever color bell pepper you enjoy the most for this recipe. Green bell peppers are the least ripe, while red is the ripest and juiciest. Yellow and orange bell peppers are somewhere in the middle with yellow being known as the sweetest.
A rotisserie chicken is perfect for this recipe. Alternatively, you could cook your own chicken breasts and/or thighs, or use leftovers from another meal.
We partially bake the peppers to soften them up. We do this because the filling is already cooked and just requires heating up. If you like your peppers with more of a crunch, you can stuff them raw without precooking.
