Pressure Cooker Chicken Cacciatore

I modified this recipe from one I found in Lorna Sass's book, "Pressure Perfect." Tomato sauce has a high sugar content,and it burns easily. I find it's a good idea not to let tomato sauce come in contact with the bottom of the pressure cooker. I just add the cooked vegetables to the pressure cooker, then the chicken, and then the pasta sauce, without stirring.
