I'm a feta fan too. I roll the chicken breasts up in a mixture of feta, chopped walnuts & parsley. Then dredge in seasoned flour, egg & milk and seasoned flour mixture again. Saute in oil, butter and lemon juice, and sprinkle more parsley over the top. Maybe, next time, I may add some white wine (& mushrooms). Thanks for the tip about feta under the skin. Will have to give that a go.
Coast, didn't mean to take away from your recipe. Sometimes we get carried away talking about food. lol. Saved to my memory.
