Pressure Cooker Chicken with Potatoes and Green Beans

I just got a new pressure cooker and needed to try it out. I found a recipe in the instruction booklet and changed it a little.  We had a friend in town and I warned him it was the first time I was trying out the thing and we may have to order pizza.  Turns out he doesn't really like chicken breasts but LOVED this recipe.  In fact,  he now wants to get his wife one for Christmas.

5 chicken breasts, boneless
2 jars Marsala sauce from Trader Joe's
3 Yukon potatoes, washed and quartered
2 large handfuls of green beans, trimmed and washed
2 Tablespoons olive oil

Turn electric pressure cooker to Browning.  Add olive oil and chicken breasts.  Cook until browned, about 10 minutes, turning halfway.  Remove from cooker and add trivet.
Pour in jars of sauce and place chicken on top of trivet.  Place potatoes on top of chicken and green beans on top of potatoes.
Select High Pressure and set timer to 11 minutes.  When audible beep sounds, use Quick Pressure Release to release pressure.  When float valve drops, remove lid carefully, tilting away from you to allow steam to disperse.  Leave on warm until ready to serve.
