I saw someone make this on the tellie... My variation goes:
Combine a cup of nonfat plain yogurt with S&P, garlic and your favorite herbs and seasonings. I usually just go with some rosemary and or thyme, chives, maybe some lemon juice, mustard, cayenne, whatever.
Coat your chicken breasts and let them tenderize in the yogurt mixture in the fridge overnight.
Wipe the yogurt off the breasts into a bowl. Whisk in 2 egg whites with the marinade and dip the chicken breasts back in the marinade to coat. Roll each coated breast in a a combination of coarsely crushed cornflakes and wheat crackers with cayenne and seasoned salt (On TV they also used sesame seeds with the crumbs). Bake on oil-sprayed baking sheet, uncovered, 45 min at 375.
Voila! Doesn't taste like REAL fried chicken, but good for a healthy alternative.
