Using leftover boiled meat to make a Philadelphia sandwich

In butter and oil, we sauté the meat cubes as they are until they take on color and we start to crumble them or we make them mushy with a fork and sauté them until they take on color. The difference between the two is the degree of roasting of the meat that you like

In its place, we sauté the onions and peppers, if available, until they are tender, then we add the spices and the meat and the sauce used and add a little water and leave them on a low heat and make sandwiches out of them and grease the bread with butter and put the cheese slices and put them under the grill for a minute until the cheese melts and the bread takes on a nice color
