Tomato Pie (Hot)

Slice a good-sized onion thinly, blanch it, and fry in fat till lightly browned. Take 1 lb. of ripe tomatoes, skin and cut in slices. Place a layer of onions in the bottom of the pie dish with a good seasoning of salt and pepper, then a layer of tomatoes, with white breadcrumbs scattered over and a few pieces of butter, and so on until the dish is almost full. Have ready some well-mashed potatoes, and spread thickly over so as to form a crust, and bake until brown.
