Heat 2 Tbs. of the olive oil in a skillet over medium heat until it shimmers. Add the chicken slices and brown them on both sides, until just barely cooked throughout.

Heat goat cheese, cream cheese and soy sauce in a microwave oven at 30% power, stirring after a minute, until it's warm and smooth. Thin the mixture with chicken stock until it has the consistency of a dipping sauce.
