Creamed Tuna Fish on Toast

This is a variation on "SOS" or the famous creamed dried beef but using canned tuna instead of the beef. It can be a quick dinner, or, as my daughter and I prefer, breakfast. Especially good on a tender stomach. Place one can of drained tuna in a frying pan. I prefer oil packed because the oil helps make the roux to thicken it but if you prefer water packed tuna, it works as well. Add 4T flour and stir the mixture until the tuna just begins to brown. Slowly add milk until the consistancy you wish is reached. Serve on toast garnished with some fresh parsley.
