There are 3 things i use cube steaks for,
1 you take some flour salt and pepper and bread it and then bake it quickly or put it in a frying pan and cook it fast. theres no set temp about 400-450 F until the digital thermometer says its good. Another is same as above but with shake n bake

last you can cook them in a crock pot with large onion chunks and potatos quartered or eighthed, season with a can or 2 of cream of mushroom soup.
