Yum! Very creative! There's this Eastern European beet salad I like to get sometimes that's more like a chunky beet spread. I think it's mostly beets and sour cream but it's so yummy! I bet it would make a nice finger sandwich filling. Normally I eat it with pierogis.

I get it from the European stall in the downstairs of St. Lawrence Market in case you're curious to try it. The store has a very generic sounding name like "European Foods" and it's kind of in the middle of the market behind a juice store. I always buy bags of their frozen pierogies to take home too.
