What a great appetizer! Roast beef and cheese sandwiched between cucumber slices. I might even put cucumber on the bottom, roast beef in the middle, and then top with cheese. Maybe a little mayo and mustard on the roast beef!
Mediterranean Cucumber Cups: These little cuties stuffed with a Greek-salad style mixture make for a very tasty party treat and a healthy spin on traditional finger foods. Could also fill with hummus, chicken or tuna salad.
