i got so many compliments on this meal. spinach, feta, garlic, panko....seriously. how bad could that be?. sad thing is, i never even tasted it. this stuffing mixture would go great with a pork chop, as well. start by heating a pan with a little olive oil. add 1/2 of a onion, diced. saute for 5 minutes, until soft, then add 3 gloves of minced garlic. cook for one minute. transfer to a bowl. in the same pan, add 4 cups of fresh spinach and saute until wilted, about 3 minutes. drain and squeeze out the excess water. add to the bowl with the onions and garlic. sprinkle with salt, pepper and fresh grated nutmeg. again, using the same pan, add 1 cup of whole wheat panko and 2 tablespoons of olive oil, one small glove of minced garlic, and a teaspoon of dried oregano. toss and set aside. now the unpleasant part. clean the chicken breasts. ugh. once clean, and i mean clean - no signs of anything but meat! split each chicken breast across, but not all the way through, and open it like a book. pound out the breast carefully, you don't want to make them too thin, or create any holes in the meat. sprinkle with salt and pepper, and stuff 1/4 of the mixture in each breast (4 total). put the chicken breast in a baking dish and top with the panko mixture. bake in a 425 oven for 23 minutes. serve this with a salad and you have got a really well balanced meal.
