Perfect for a neighborhood gathering or a pretty buffet. The watermelon and labneh together with the cucumber make a super-pleasurable bite, and practically guilt-free! Assemble the bites just before serving.
Cut the watermelon crosswise into slices about 1-inch thick. Use a small cutter, about 1 1/2 to 2 inches, to cut out bite-sized disks from the watermelon.
Top each disk with a small dollop of labneh (about 1/2 teaspoon).
Quarter the cucumber into spears lengthwise, and cut the spears into 1/4-inch wedges. Top each dollop of labneh with a cucumber wedge.
Sprinkle the bites with sea salt just before serving (to avoid too much water coming out of the melon and the labneh). Serve the bites chilled.
