Wash and dry cucumbers. Slice into 1/2-inch thick rounds.
Using a small spoon or melon baller, scoop a shallow well in the center of each round, being careful not to go all the way through.
Pat the inside of each well dry with a paper towel to remove excess moisture.
Spoon or pipe hummus generously into each cucumber well.
Sprinkle with paprika or za'atar. Garnish with a small sprig of fresh dill or a few parsley leaves.
Add an optional drizzle of olive oil and a pinch of flaky sea salt if desired.
Arrange on a platter and serve immediately, or cover and refrigerate for up to 2 hours before serving.
