Place the cucumbers on a cutting board and use a meat mallet or heavy flat object to pound the cucumbers until they smash and flatten slightly. Slice each cucumber in half lengthwise, then slice into 1 ½-inch thick slices and pound again.

Transfer the smashed sliced cucumbers to a strainer set over a bowl. Sprinkle the cucumber with salt and mix until well combined. Set for 30 minutes to allow the liquid to drain from the cucumber.

Meanwhile make the dressing by whisking together the shallot, lemon juice, olive oil, mint, sumac and black pepper in a serving bowl.

Use a paper towel to dab the cucumber dry. Transfer the dried cucumber on top of the dressing. Sprinkle the feta cheese and toasted sesame seeds on top.
