Stir 3 tablespoonfuls of vinegar very gradually into 6 tablespoonfuls of oil and a dash of paprika. Add salt, if the beans have not been seasoned. The oil and vinegar will not unite perfectly. Pour gradually over a pint of cold baked beans such portions of the dressing as they will absorb, toss together and arrange on a serving dish. Make a border of sliced tomatoes around the beans and over these pour the rest of the dressing.
