PROTOSE STEAK A LA TARTARE

Put the butter in a saucepan and set on the range. When hot, add the onion and cook until brown; add the minced protose, a pinch of salt, and mix. Form into balls, making a depression in each ball, and drop an egg yolk in each depression. Bake until the eggs are done. Chop the onions and olives, add the mayonnaise, and use as a garnish.
