Polar sunday

I love sunday mornings.
Usually I have a good saturdaynight party/drink/birthday/date/concert/... which allows me to stay in bed on sunday till at least ten o'clock (yes, that's late for me). And then, after we manage to get out of bed, get dressed and drink coffee, we run outside into the sun to get breakfast outdoors.
Seriously, is there anything better? 

This is polar bread, filled with smoked beef, tomatoes and horseradish sauce.

I really really really want to make this bread, once. Here's a way to do it!
