Place butter, mustard, parsley, and garlic in food processor. Form a thick paste.
Season breast with salt and pepper; then spread with mixture. Wrap the entire breast in aluminum foil.
On the Instant Vortex control panel, press Air Fry, then set time to 45 Minutes and temperature to 390°F (200°C).
When the time is up, open the aluminum foil on top and set time for another 30 Minutes, at the same temperature, to brown the chicken.
To a saucepan add the butter, and when it begins to melt, add the flour, stirring constantly, until it forms a paste. Add the juices remaining in the aluminum foil from the turkey and white wine. Thicken while stirring over low heat.
Serve over sliced turkey and garnish with cranberries and walnuts.
