Keep in mind that if you're going to add chicken, you might want to increase the number of potatoes and bell peppers to balance it out. We tend to use about 6 potatoes and 3 bell peppers total. We also bump up the olive oil to about 5 tablespoons, too. Eventually, you kind of eye-ball everything and improvise as you go along to see what best suits your needs. However, bumping up everything else means your skillets are going to overflow, so good luck.
