Cut brown bread into rounds or circles with an ordinary cake cutter. Chop the mutton rather fine; add the olive oil, salt, and paprika. Peel the tomatoes, cut them into slices and push out the seeds. Put a slice of tomato on top of a round of bread, fill the space from which you have taken the seeds with the mutton mixture; put on top another round of buttered bread, and press the two together. You may, if you like, put on top of the tomato a lettuce leaf, and in the center of that half a teaspoonful of mayonnaise dressing. Nice for luncheon on a warm day.
