Also cut the tomatoes into slices and place between the cucumber slices. Divide the remaining vegetables into bite-sized pieces and place around the cucumber.
Shape the red pepper into small round eyes and a tongue, place on the tip of the cucumber. Chop the onion and chives, mix with the quark and season. Serve the quark separately in a bowl.
