Backstrap is one of the good cuts. Cut it into steaks and cook on the grill like you would a filet!. For chicken fried, cut a steak off the ham, pound it tender, bread, fry, and cover in cream gravy..YUM!
I have found the muscles out of the hind legs to make better/more tender and bigger steaks than the backstrap itself, but I will grill, sear in cast iron, or chicken fry any of it.
My favorite is to cut tenderloins into medallions and sear in cast iron, seasoned with salt course pepper and some garlic powder and served very rare.
