I have a bunch of beets I'm thinking of roasting or boiling and turning into beet tea sandwiches for a party. A quick survey of the Internet tubes revealed no ideas! I munched a delicious roasted beet-blue cheese-walnut sandwich at a local lunch spot, but I imagine a tea sandwich would be more delicate. I've considered thinly sliced beets with horseradish-butter, or cucumber beet cream cheese ribbon sandwiches. Any ideas from the Serious Eats Crowd?
