egg dish

Additional guests have confirmed their attendance for this year's christmas gathering. I shall have to add to the menu. I am thinking of a simple dish and would like your suggestions. I shall serve boiled eggs, cut into half after shelling them . I will scoop out the egg yolks from all the eggs.Then the while halves of the boiled eggs act as little plates but I am not sure what I shall put in them. Does spicy tuna sound appetising? Or crispy chopped bacon? Will value your suggestions . Thanks.
