Cook chicken in olive oil till nearly cooked.

Then cook onions till soft and add mushrooms till soft.

Add mustard and flour and stir till all is coated.

Pour stock in a little at a time, remember you can always add, but can never take out once added. :)

Pour untill it thickens like a gravy and let simmer for 15 minutes.

Add the chicken, sour cream and seasonings. Let cook till chicken is warmed and fully cooked.

May layer over rice or eat as is.

Serve and Enjoy :)
