Beef sandwich toast with boiled potatoes is an easy kid friendly Kerala style sandwich toast, usually made for kids lunch box. Amma used to make this for my two brothers and me to take to school, she will sometimes fill with left over beef cutlets . I am sometimes lazy to roll up cutlets and so I fill the bread with cutlet mix and slather with good old butter and toast in my old gas toaster and the result is crunchy buttery toast....my kids love them. This cutlet mix is very versatile; I refrigerate it after adding boiled potatoes; and sometimes spread on Indian flatbread / roti and roll and heat it up with a dollop of butter or sometimes I make keema paratha with the cutlet mix minus the potatoes (with potato also its yum). Method: Pressure cook half kg beef with potatoes, vinegar, and salt for 15 to 20 min, evaporate if there is any water left on high flame. Allow it to cool and then mince it.
