Hi Heber,
Is she fussy about how the chicken is cooked, as in she likes it crumbed and fried? Or does she like it skin on?
You'll have to loose the skin, and find other ways than frying to cook it.
Grilling (broiling) is good, can use spices like paprika and pepper to give it some colour. Can marinade in lemon, rosemary and a little EVOO (no cholesterol in that) then grill, sprinkle with some parsley to make it prettier. Poaching is ideal, comes out nice n soft.
Try a roulade - gently beat out a boneless (and skinless!) breast or thigh very thin between some cling wrap. Steam some spinach, lay this on top of the chicken, roll up and secure with string/ toothpicks and steam till done. Remove string/ toothpicks and carve into pieces across the roll - looks quite pretty, little swirls of green and white. You can experiment with the filling depending on what she likes, make it even more colourful by using something red.
If she really likes it crumbed, instead of using egg wash use a mild mustard then crumb it, and oven-bake. Use a little EVOO spray on the pan.
And of course lots of steamed veg and salads - mind the dressings!
Good luck - give the pork and turkey a go too, you can substitute them pretty well as above
