In a shallow plastic container or bowl, whisk together all the marinade ingredients until combined. Add in the sliced cucumbers and toss, making sure the cucumbers are completely coated in the liquid.
(Alternatively, you can add the cucumbers to a glass jar and pour the marinade over them.)
Tightly cover and chill in the fridge overnight (see note.)
You can either keep them in the fridge and munch on them like pickles, or if serving as a salad, drain the cucumbers and reserve a bit of the marinade. Transfer to a shallow bowl and drizzle with the reserved marinade. Enjoy cold.
