Roll out a sheet of pastry and cut out a circle with a cookie cutter. Cook your sausage and drain it...while it's hot stir in the cream cheese and add a dash of hot sauce to taste. Spoon the mixture onto the pastry and fold it up in a half moon shape. Seal the edges and brush with egg whites. Sprinkle a few poppy seeds on top and bake until golden brown at 350 degrees.
