I am looking for some recipes for homemade cat food?

Since the problem with the commercial cat food, I would like to make my own, using good quality meat, chicken and fish. I do feed tuna on occasion, using a good brand of albacore low sodium, water pack, for my 15 year old male, however I am aware that they can become malnourished if they do not get the proper vitamins, taurine, etc. They also eat a good brand of dry food. Any help would be appreciated.
