Zesty Chicken in the Instant Pot

I really have no business posting this because it is Shonna's recipe.  In fact, she made it up.  Shonna has had a pressure cooker for several years and is kind of an expert instant potter.  She uses hers all the time and really knows how to use it.  This recipe was delicious and easy.  Her kids love "chicken and rice."

Zesty Chicken in the Instant Pot
4 frozen boneless, skinless chicken breasts
Sauce
1 packet Grill Mates Zesty Herb Marinade mix
3 T. olive oil
3 T. vinegar
1/3 cup water


For later
1 cup plain yogurt or sour cream
Cooked rice

Mix together the sauce ingredients.  Put the frozen chicken in the instant pot.  Pour the sauce over the top. Cook on poultry setting for13-15 minutes.  Let pressure reduce.  Take chicken out and shred with beaters (or you can leave whole or cut in chunks.)  Take out some of the sauce and put in a measuring cup.  Add a couple Tablespoons of flour and whisk together.  Add back into the pot.  Whisk together while it cooks and thickens on the saute' setting.  Add 1 cup plain yogurt or 1 cup sour cream.  Whisk together.  Add chicken back in.  Serve over hot rice.
